Twitter today finalized in San Francisco district court an agreement with the makers of TweetAdder software that bars them from making future software designed to violate Twitter’s terms of service, according to court documents.
TweetAdder released a new version of its software last week that eliminates a previous feature that allowed users to follow a set of users in bulk. As part of the agreement, the company must shut down all previous versions of the software.
Twitter sued the makers of TweetAdder in April 2012 amid a spate of lawsuits designed to shut down businesses and individuals who facilitated spamming on the social network.
At the time, Twitter said it had targeted “the most aggressive tool providers and spammers.”
“We’re going straight to the source. By shutting down tool providers, we will prevent other spammers from having these services at their disposal. 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 said last April.
The terms of the deal remain confidential. Each party will pay its own attorneys’ fees.
