I think the general consensus seems to be bot and/or spam accounts being removed but I haven’t seen evidence of it. Anecdotally I have seen many people say it feels more busy around Lemmy lately but I haven’t been here long enough to know myself. It is a curious one though.

If it is genuine then I suppose it could be a typical cycle for platforms that get raided by another, in this case an exodus from reddit to Lemmy - then after the dust settles some people decide they don’t like it after all and go back or elsewhere.

I don’t think that is a bad sign though that is a natural cycle and as long as some people remain then it shows overall growth.
