The implication here is that anarchists are relatively common on the fediverse, and if so, it wouldn't be the first time I've seen this idea expressed.
But the thing is that I am an anarchist, and I've been keeping my eyes open, and I haven't seen any other anarchists here. LOTS of authoritarian leftists, ranging from naive social democrats to full-blown "submit or die" tankies, but not one single other anarchist.
So are you actually trying to say that anarchists are common here? And if so, where are they?
This seems like a weirdly unnecessary way to not quite manage to duplicate what lemmy has been designed to do.
You go to the community list for your instance and do a search on the URL of the community you're interested in. Then (assuming that your instance is federated with the other one) your instance will create its own mirror of the community, and you're done.
