Same for me! And tbh I've never unfollowed anyone for any reason except posting or reblogging obnoxious takes on something I care about. But even a few years ago, I started noticing the patterns in unfollows:
#1 thing that drops the follower count: getting really into an older fandom, or a relatively small one. (Most glaring when I relapse into S1 LOK feelings.)
#2 thing: not posting or infrequently posting. Usually 3-4 days of silence is enough to start it.
#3 thing: responding brusquely about anything (regardless of what led to it).
(Follows are less predictable, but generally come when one of my post makes the rounds, or when I stake a position on some divisive fandom issue that have both a lot of opponents and supporters.)
