In an attempt to get rid of the flood of spam across Twitter, the company's filed a lawsuit agaisnt several companies it says are some of the worst offenders.
It's suing the companies behind TweetAttacks, TweetAdder and TweetBuddy, as well as James Lucero of Justinlover.info and Garland Harris of Troption.com, in a San Francisco federal court.
The companies, it says, have been engaging in activities ranging from offering spam broadcasting software to falsely promising to get ustin Bieber to follow their accounts.
"With this suit, we’re going straight to the source. By shutting down tool providers, we will prevent other spammers from having these services at their disposal," says Twitter on the company blog.
"Further, we hope the suit acts as a deterrent to other spammers, demonstrating the strength of our commitment to keep them off Twitter."
The company says it's also introduced new anti-spam measures to try and combat a new type of @ mention spam. It's also now using its link shortener to analyze whether a tweeted link leads to malware or malicious content.
In its complaint, it alleges that it's had to spend a total of over $700,000 on anti-spam measures as a result of the defendants' activities, and calls for monetary damages.
"We are committed to fighting spam on all fronts, by continuing to grow our anti-spam team and using every tool at our disposal to shut down spammers," it says.
