There have been sightings of Twitter recommending user accounts to UNFOLLOW.

Slate confirmed this with Twitter but they refused to say if the new suggestions will be rolled out live.

The test appears to be part of Twitter’s ongoing effort to boost engagement and user satisfaction by using software to personalize their feeds. The company’s timeline ranking algorithm and “In Case You Missed It” features have helped to revive the company’s engagement metrics somewhat over the past year.
