Lichess has been removing my follows

I was a bit bewildered today to discover that a healthy number of players I've followed for a long time have been removed from my follow list. Do follows expire after a certain period of time, is there only a certain number of follows allowed, or is this just a weird bug?

Yea, lichess has a 300 follow-limit which is really annoying... I lost the first people I ever followed like that, but hopefully found them all back. My first ever follow now on lichess is FischyVishy (so I have to keep purging to stop the auto-purge kicking in).

oh lol thanks okei good to know
