More Details on Twitter Limits

0 #

Twitter has revealed more details about the limits that they recently put in place to prevent people from abusing the Twitter network. The details were posted in FAQ format on Get Satisfaction. They continue to be intentionally vague about the specifics of the Following limits. Thanks again to @mdy for the tip.

From the Get Satisfaction post:

I hit a Twitter limit; what does that mean, and what do I do?

If you hit a Twitter limit, it means you’ve exceeded the maximum number of times allotted to perform a given action on Twitter. In other words, you can only do things so many times before you have to take a break.

What are the limits?

We’re starting with a few limits based on various parameters, and we’ll be adding more as time goes on. We reveal some limits only when you reach them, and tell you about others in advance. Twitter applies limits to any person who reaches:

* 1,000 total updates per day, on any and all devices
* 250 total direct messages per day, on any and devices
* 70 API requests per hour
* Maximum number of follow attempts in a day

Follow limits are based on several things, one of which is our belief in a person’s good standing and intention. The behind-the-scenes portion of follow limiting varies by account, relationship, and changes over time.

Based on current behavior in the Twitter community, we’ve concluded that this is both fair and reasonable. While we figure out what works best for everyone, the limits may change occasionally, but this is the nucleus and future limits will be based upon the success of these.

How will I be affected by the limits?

People using multiple API clients at once may see the per hour API request limit, as usual. Aside from that, most people will not be affected. If you do reach a limit, we’ll let you know, and after 24 hours from the last action, the limit is automatically removed.

Why Twitter Limits?

Starting with 140 characters per update, Twitter has always been about limits, embracing the idea that constraint inspires creativity. The new limits do not restrain reasonable usage, and thus, will not affect most people. We do, however, hope to discourage unreasonable usage that alarms the people affected by it. These limits also alleviate some of the existing strain on the invisible part of Twitter: fewer robots and whales.

I’m not satisfied!

Did this Screencast Launch Twitter Spam?

2 #

I’ve come across a screencast by an internet marketer that introduces micro-blogging as a new frontier for marketing. In this video he talks about Twitter, Pownce, and Jaiku but the primary focus is on Twitter. I’ve said before that I’m not against using Twitter for marketing purposes. So why does this video bother me?

1) The video was produced on March 17th (notice the St. Patrick’s Day logo on the Google page at the start of the video). This is a couple of weeks before I started to notice a big increase in spam followers on Twitter (I started this blog on March 31st). I’m not sure how many people attended the seminar where this demonstration was given but based on the timing of it, it appears to have some connection to the escalation of spam on Twitter.

2) It’s clear from the video that this marketer is not using micro-blogging services to communicate with other people. The primary goal is to get indexed by Google and drive clicks to affiliate sites and make money. That’s it. There is literally no mention of using Twitter to engage with customers, listen to what they are saying, and all of the other “soft sell” techniques that companies like Zappos, Comcast, Pandora, and many other companies are using very effectively.

3) There are several references in this video to using automation tools to generate tweets and follow other people on Twitter. Biz Stone from Twitter recently referred to these types of tools as a contributor to their stability issues.

The good news is that Twitter has recently taken steps to detect spam accounts on Twitter and terminate accounts that have been determined to be spammers. It remains to be seen how effective Twitter’s anti-spam tactics will be.

The video runs for about 17 minutes. Below are some highlights in case you want to skip around.

2:35 - Talks about how Google indexes content from Twitter and other micro-blogging sites. “The spiders follow, your sites will get indexed, your properties will rank, and you’re just going to make more money.”

3:38 - Compares following people on Twitter to friending people on MySpace.

4:29 - Talks about how he made all of his money on MySpace before a friend adding tool was available.

5:00 - Talks about how you can get a competitive advantage by getting into Twitter, Jaiku, and Pownce early.

5:20 - Shows how he set up the infamous @BarackObama4 twitter profile on Twitter (a well known spam account)

5:48 - Makes a reference to an automated tool to create almost 6,800 updates on @BarackObama4

6:40 - Shows how he set up the HillaryClinton5 (another well known spam account)

7:20 - Talks about Email marketing is almost dead because of spam filters and how micro-blogging is a new opportunity.

7:55 - Talks about pinging RSS feeds to get more attention from search engines

8:39 - Shows how he set up @toshibalcd to “drop links” to an affiliate page selling Toshiba televisions.

10:00 - Another reference to automated tools

10:12 - Shows Tumblr

11:15 - Shows Pownce

12:24 - Shows how search engines are indexing micro-blogging content

13:45 - Shows an affiliate tracking tool that shows how many clicks he has gotten for the various micro-blogging campaigns that he has “niched out”

14:50 - Another reference to automated tools

15:05 - Call to action to get involved today and “take over this traffic”.

15:15 - Another reference to automated tools

15:40 - Gives a sales pitch for automation tools

15:55 - In reference to using automated tools, says that you have to “get your hands a little dirty”

Here is a screenshot from the video:

Twitter Purging Spammers?

A scan of the excellent Twitter search site Summize shows a large amount of people tweeting about lost followers over the past few days. No one knows for sure what is going on but a few have keyed in on the idea that Twitter may simply be deleting the accounts of users it marked as spammers.

Twitter Discusses Bots/Spammers with ZDnet

Biz Stone from Twitter discusses bots / spammers with ZDNet’s Jennifer Leggio.

Q. (ZDNet) I’ve seen some concerns pop up lately about the combination of Twitter bots / spammers and URL redirection sites (a la TinyURL). Are you concerned about an infiltration of malicious links into the Twitter feed? Have you considered creating a way to post smaller links that allows users to preview the originating URL?

A. (Biz Stone) User security is absolutely a concern and we’re working to make the interface safer in that regard. We are looking into other ways to display shared links, for example noting whether a link goes to a picture or a video or some other media element. While more a feature, this could help in addressing some of the risk with the URL redirection.

Q. (ZDNet) What about the bots? Wouldn’t eliminating some of these offenders help both improve the user experience and diminish some of the pings to the API?

A. (Biz Stone) Absolutely and we’re working on that now. We analyze friend/follower ratios and frequency of updates and this alerts us to whether or not something is spam. We’re very intolerant and have no problem deleting massive amounts of accounts doing anything of that nature. It ruins the tool and makes it inefficient.

Twitter Rolls Out Following and Update Limits

3 #

Twitter user mdy spotted a new Twitter Help page called 4.6 Following and Update Limits. The specifics of these new limits are intentionally vague but it’s clear that they are targeted directly to spammers who mass-follow other Twitter users in a short amount of time or blast out updates every few seconds.

I think this is great news. Matt Cutts (Google) recently spoke about anti-spam measures at the Web 2.0 Expo in San Francisco. He says that one of the best countermeasures against spammers is to frustrate them and cost them time. This latest move by Twitter is sure to do that. But like any anti-spam technique there are sure to be some false positives. If you feel like you have been unfairly shackled with these new limits you can contact Twitter support and plead your case.

Here is the complete text of the new Help page as of June 8, 2008:

4.6. Following and Update Limits

It is possible to get into a state with your Twitter account where you are not able to perform some action (at least for some period of time) because you’ve hit a limit. There are multiple types of Twitter system limits, ranging from the number of updates in a given time period to the number of requests to follow other accounts. There may be other types of limits in the future.

Why do these limits exist?

Twitter has always embraced the idea that constraint inspires creativity. The service has thrived because of limits–most notably, that of 140 characters per update. In general, we encourage experimenting with new uses for Twitter. However, without system limitations in place it becomes possible for some activities to place excessive strain on the system to the detriment of others.

What are the limits, specifically?

The limits are based on multiple parameters–not a single metric. Because the limits are in part meant to curtail nefarious behavior, we are not revealing the specifics of how they are reached. Please note that these limits are sure to change as we figure out what works. We’ve taken a best guess to get started, but Twitter is still evolving and new uses are being invented all the time.

How will I be affected?

The good news is, it’s highly unlikely you will be affected. The limits were designed to not affect the vast majority of people. If you got to this page from somewhere other than a message in Twitter that says you hit a limit, chances are you’ll never have to think about it again. On the flip side, you probably will be effected (unbeknownst to you) in positive ways by having a better-working Twitter.

Did you reach the limit in error?

If you think you’re hitting the limits unfairly or you have a legitimate need to go over please contact Twitter support and explain your situation.

Twitter Shutting Down New Follower Email for Spammers

0 #

Have you noticed that you’re not getting email alerts for some of your recent followers on Twitter? Well, most likely those new followers are suspected spammers. Twitter has recently taken steps to turn off this email if the new follower is a suspected spammer.

This is a comment from Twitter co-founder Ev Williams on a recent blog on the Structured Thoughts blog:

This is actually by design. We have a flag in our system that disables email notifications when people trip a certain follower ratio (among other parameters). This is to reduce potential annoyance. We also then check these accounts and sometimes disable them altogether.

For most people who are automating mass following, their whole point is to get the email sent, so they will get attention and possibly followed back. But we realize this is not ideal, because you may want the notification.

We have a plan to put more limitations in place.
