I've been curious about this; is rotation or segregated accounts more complicated when operating in the Fediverse? It seems like you're meant to have a single identity across everything.
Not particularly. I spun up accounts on quite a few different lemmy instances yesterday when certain instances were getting hammered by traffic spikes. Things seem to have settled down now, but it seems like jumping to a new account is very easy. I worry that it will make it harder to deal with trolls and spammers though if they can just create a new account on another instance at will.
