I feel like I’ve been seeing more posts and comments though, and looking at those, they seem to still be rising (although probably influenced by bots).
I wonder if the spike of active user may be caused by people first trying it out (then giving up), followed up by people making several accounts on different instances before settling for one or two.
I come back every year or so and play for a month or two each time, still haven’t spent money on it (but starting to think I should, to support the devs)
