@edent we used to call this “Kreis-Hygiene” / “Circle-Hygiene” going back to G+ when we “circled” friends.
It’s like teeth brushing but with followings. It has to be done on occasion. Especially over the last year 🙁
This is not only to sort out far right voters or Covid deniers. Often it’s also to find out that a dear account went silent and moved on and the note about it was simply missed. Nobody re-reads yesterdays news.
