The Best Practices section contains specific guidelines about Twitter Spam:

Don’t spam people. Twitter’s following model means that you have to respect the interests and desires of other people here or they’ll unfollow you. The most common way to run afoul of that understanding—and to thus look like a spammer—is to send unsolicited @messages or DMs, particularly when you include a promotional link.

Of course, if you run an account that focuses explicitly on sharing exclusive coupon codes or sale information, you’re probably just fine posting promos. But tread carefully, and consider explaining in your bio or background how the account works.

Tip: You can test the waters by sending just a few promos to start, and then continuing only if people show interest.

To make sure you’re not spamming folks, we also suggest you avoid the following:

• Posting duplicate updates to an account: Posting the same update over and over throughout the day is considered spammy and a possible violation of our terms of service.
• Cross-posting duplicate updates to multiple accounts: If you post the same update to multiple accounts, you could violate our terms of service.
• Following churn: Following and unfollowing the same people repeatedly, as well as following and unfollowing those who don’t follow back, are both violations of our terms of service.

Tip: Think you’ve encountered a spammer? Let us know, and we’ll look into the account. You can alert us to spam profiles by sending a direct message to @spam! In addition, you can block the spammer by heading to their account page, and on the right side, clicking the block link (they won’t know you’ve blocked them).

Some people are skeptical about Twitter 101.  Robert Scoble posted this comment on TechCrunch:

I thought that Twitter was so simple that it doesn’t need an instruction manual. Is this why Twitter is going to beat Facebook? Yikes.

On the other hand, today I saw http://www.twitpay.me and it lets you get paid on Twitter. Now THAT is something that will get businesses excited!

I’d rather Twitter do what Apple is doing: focus on featuring the best uses of Twitter (in a directory/store) and stop with trying to make a guide. Is there a guide like this for the iPhone? No.

Twitter has a control problem: they seem to want to reward people for certain behaviors (ala the Suggested User List, which has mostly brands and celebrities on it) while trying to get the rest of us to “behave” and “Twitter properly.” That isn’t the attitude of a mature platform.

Oh, and why aren’t they fixing search instead of doing this lame stuff? Search isn’t indexing old tweets and is full of spam and noise. Fix that stuff and businesses will figure out the model on their own.

I’m less skeptical.  Some businesses don’t get Twitter right away and I’m in favor of any efforts that point businesses in the right direction.

The results are in and as of today, over 75% of the respondants are in favor of Twitter moderating Trending Topics. 16% say No and 8% aren’t sure.

I was expecting more of an equal split on this.  On the one hand, people recognize that Twitter needs to take a stance against obvious spam attacks againt Trending Topics (such as the recent attack “allegedely” by 4chan).  But at the same time, some critics are claiming that legitimate Twitter users are getting caught up in Twitter’s anti-spam dragnet.  Twitter recently admitted to accidentally suspending accounts as a result of a spam clean-up effort.  And there have been recent accusations that Twitter is overdoing their anti-spam efforts and filtering out legitimate tweets from Twitter search results.

My opinion?  I don’t think Twitter can afford to sit back and do nothing.  Louis Gray sent this tweet out after a recent attack against Trending Topics: “One need only see the top trending topic on Twitter now to recognize at times, the inmates run the asylum. Embarrassing.”. Twitter can’t afford to be embarrassed like this.  With that said, Twitter needs to refine their anti-spam algorithms and cut down on the false positives.  This raises a question.  Why do we have dozens of developers creating nearly identical Twitter clients but no major third party services attacking the problem of Twitter Spam?  Who is going to create the Akismet for micro-blogging?

From the ReadWriteWeb post:

“At the end of the day, we agree with Twitter’s decision to pull the obviously forced hashtag from the trends section just as they did the last time a bunch of folks thought they would have some fun by tweeting other offensive words and phrases. But these incidents have made us wonder: has Twitter trends outlived its ability to function properly as an entirely algorithm-based service? Given how many people rely on Twitter trends to track hot topics and breaking news, the section will be under constant attack from those who want to use the algorithm for their own purposes…and not necessarily good ones.

In some cases, like the latest 4chan move, the term-made-trend will be a somewhat offensive, but ultimately harmless prank. In other cases, the trends will be courtesy of some marketer pushing their hashtag up through the ranks thanks to their latest “tweet-to-win” contest. But do either of these cases represent an organic news-based trend that deserves the spotlight? Perhaps not.”

If Twitter takes this approach, there’s no doubt that they will take heat for filtering out terms that are in a gray area.  In fact, those accusations have already started.

@TEDChris has a great post today analyzing this marketing tactic and questioning if it’s really worth polluting your Twitter stream when the chances of winning are so small.

- Would you post an ad for a random company through your friends’ doors in return for for a 1 in 200,000 chance of winning a computer? (If you did that every single day your whole life, chances are still overwhelming that you’d never win… …and even more overwhelming that you’d end up with no friends .)

- Assuming each tweet gets seen on average by 20 people, Moonfruit are buying media “impressions” here at a CPM rate of less than 50 cents… equivalent to ‘junk’ space online, and easily low enough to tempt in a lot of other companies.

- Bottom line… our words and connections are being bought on the cheap! And unless the Twitterverse wises up, we’ll end up getting deluged with hashtag spam.

One Fine Jay compares these types of contests to beautiful highways getting ruined by too many billboards.

Just as the plethora of billboards ruined the skylines of Route 66 and other great highways of the past, advertising today in its most blatant forms has invaded any mental domain imaginable. Nowhere is safe, definitely not Twitter. It’s no surprise that online marketing and advertising would pounce on a free medium to promote their wares.

He goes on to describe how these types of contests put us in the difficult position of deciding whether or not to unfollow people who clutter their twitter-stream with these meaningless hashtags.

… Hashtag contests are turning the people I following into spammers.

This, too, is different from a lottery. Games of chance where participants pay to play are usually regulated. Free raffles are usually not. Take note that I am not yet ready to call shenanigans on this, but instead of paid participation, people offer up their time. In a world of free content all vying for our attention, our time remains the most valuable asset we are all too willing to give up.

Moonfruit’s campaign and the clones it will spawn will lead to a general degradation in the aesthetic of the Twitter stream. To a user, we have but two choices: bear through it, or unfollow someone. Getting spammed three messages at a time by half of my users is a painful thing to sit through, because I’d rather not block or unfollow these people. They are still worth following, and it is this good will that I and others extend to the people we follow that companies capitalize on whenever they do these awful contests.

Kev from Outside Lines says:

Here’s an idea for “Twitter promotion done right” – make a great product, and release it with a clever launch. If it’s smart, everyone talk about it. Get to the top of the trending topics legitimately, not by dangling carrots in front of keyboard-equiped imbeciles who don’t know better.

July 6th Update:
Moonfruit claims that Twitter has censored the #Moonfruit hashtag from Trending Topics.

I first heard about Trendrr on Fred Wilson’s excellent A VC blog. You can track up to ten phrases for free. Pro accounts range from $49 / month (30 phrases) to $999 / month (unlimited phrases and full reporting). You can follow Trendrr on Twitter here: @Trendrr.

I’ve decided to declare July 2009 as “Month of Twitter Bugs” (MoTB). I’m doing so in order to raise the awareness of the Twitter API issue I recently blogged about. MoTB could have been easily converted to any other “Month of Web2.0 service bugs”, and I hope that Twitter and other Web2.0 API providers will work closely with their API consumers to develop more secure products.
Each day I will publish a new vulnerability in a 3rd party Twitter service on the twitpwn.com web site. As those vulnerabilities can be exploited to create a Twitter worm, I’m going to give the 3rd party service provider and Twitter at-least 24 hours heads-up before I publish the vulnerability.

Today (July 1st), Aviv published the first vulnerability: MoTB #01: Multiple vulnerabilities in bit.ly service.  The good news?  The vulnerabilities were fixed in just three hours.  It’ll be interesting to see what Aviv comes up with over the next 30 days.  You can follow the progress on the TwitPwn blog or follow Aviv’s #MoTB tweets.

This guy is sending out misleading tweets that lead to a Zazzle site that peddles awful MJ RIP products.

The topics that are trending right now are a reflection of how people are feeling on this very, very sad day.

Updates:

• Trending Topics is back as of about 10:30 pm PST.
• Looks like there are some people out there who want a user preference to remove Trending Topics from the Twitter Home page.
