Let's be real. What OP really wants is for a certain moderator to not have power on a server she deems as influential. Thus, she's trying to leverage peer pressure in order to make that happen.
But the moderator can join any server or create her own as well. So trying to remove her perceived influence is basically playing whack-a-mole, and because she herself doesn't run any servers, peer pressure is an ineffective tool.
So if the moderator is that objectionable, the reasonable thing to do is either:
- block the moderator
- block all communities the moderator runs
- block LW
If neither of these options have the desired results, then I'm sorry -- that's just life.
Not at all. Trolls can be vindictive and litigious. Call-outs can result in swattings or long drawn out lawsuits.
The best way to deal with trolls is to quarantine them. That is, minimize their reach.
I assume that all servers can be compromised -- even the "good" ones. Which is why you should always consider an escape hatch. And federation itself is that escape hatch.
LW is not so big that it is immune to defederation. It's not even among the top 10 servers on the Social Web either by MAUs or total users. And you don't even need a big server to be seen. I'm on a small server (atomicpoet.org), and from my experience, it's a lot easier to be seen on the Fediverse when you run things yourself.
But "bigness" is also a reason to build more Fediverse servers and redundant communities that exist on those other servers.
