I've been asked in DM by someone why I unfollowed them. (Not a subtoot, I already answered them.)

If I did unfollow you (or didn't re-follow you after the instance switch), it can mean two things :
- I forgot. I'll probably do it later.
- I don't wanna see whatever you're talking about or boosting in my Home. Doesn't mean I won't read you on the local/federated TL (altho I rarely check those), or that I hate you or whatever.
