I think the only way around stuff like this is to have some alts hanging around. This account is an alt to the same-name lemmy.ml account, but now only the lemmy.ml account can see beehaw stuff. It's a shame, because beehaw did seem to have something good going with their more curated communities. They could have put out a call for moderators if that's what they need, but instead they decided to close the gates.

I wouldn't be afraid to make a bunch of alts. Simply having an alt account doesn't put strain on the servers. It's the using it that does. Until then, it can lie in wait, inactive, without much impact.
