Twitter is purging inactive accounts on its platform, which may free up a number of long-coveted usernames, according to recent tweets by owner Elon Musk. Though Twitter for years has promised to put more usernames back into rotation, it hadn’t yet made any large-scale effort to do so, despite having an inactive account policy in place that suggests Twitter’s users should log in at least every 30 days to keep accounts from being permanently removed.

According to Musk, Twitter’s purge is more conservative than that policy states. Instead, he says the company is purging accounts that have had “no activity at all for several years,” while also warning users that the result of the purge may mean users’ follower counts drop. That’s something that may be more noticeable on longtime Twitter accounts whose owners accumulated a large following during Twitter’s early days as a social network.
