Twitter is making changes to Tweetdeck in an effort to fight spam, the company announced on Wednesday.
As part of the changes tweetdeck users will no longer be able to select multiple accounts to tweet and retweet.
This feature was a crucial one to the tweetdeckers, who would form exclusive Tweetdeck groups in order to automatically mass-retweet each others tweets into manufactured virality.
“To be clear: Twitter prohibits any attempt to use automation for the purposes of posting or disseminating spam, and such behavior may result in enforcement action,” Yoel Roth, manager of trust and safety at Twitter, wrote in a blog post.
Roth also said the Tweetdeck changes were “an important step in ensuring we stay ahead of malicious activity targeting the crucial conversations taking place on Twitter — including elections in the United States and around the world.”
The changes will put a ban on “posting duplicative or substantially similar content, replies, or mentions over multiple accounts you control.”
The company laid out a series of specific policies and exceptions for account automation. Instead of sending the same tweet from multiple accounts, users can send one tweet and have multiple accounts retweet it, but they can’t use “bulk, aggressive, or very high-volume automated retweeting.” The ban on bulk tweeting applies regardless of whether you’re posting a bunch of duplicate tweets at once or scheduling them across a longer time period.
