X owner Elon Musk is promising to “soon” address the lack of transparency around “shadowbanning” on the social network formerly known as Twitter — that is, not outright banning a user, but making changes that ensure their content is no longer circulated and kept out of public view. In replies to users on X, Musk apologized for why the process is taking so long and explained what’s holding up X from providing this data to users.

Shadowbanning has been a topic of concern even in Twitter’s earlier days, as users didn’t know they had been penalized in this way for their tweets. When enforced, users can post to the platform as usual, but would notice their tweets simply aren’t getting the traction and replies they normally would. The topic often became politicized, as Trump and other Republicans complained that Twitter was making their tweets invisible.
