> Are you blocking instances, and on what conditions?
I block instances when they either flood or I find I don't want to have anything to do with them (I do tolerate opinions I disagree with, of course; but not patent bigotry).
And only based on evidence I gather myself, I don't trust screenshots or copy-pastes (but I understand some mod teams do, and that's ok if that's what their users want).
> I wonder how often you get complaints about wanting an instance blocked, and how you manage them.
As I said, I never got complaints. I also never got instance requests personnally; although I do sometimes see other instance admins saying they blocked a given instance. When it happens, I take a look at that instance's public pages. Usually, that's enough to make my mind, eg. because their public timeline is overrun by literal nazis and/or lolicon.
(I was looking for examples as I was writing this, and it turns out most of the nazi instances I blocked don't exist anymore. Oh well.)
The hardest part is dealing with big instances with many "well-behaved" users, but also a very lax moderation policy that tolerates trolls. So far I only banned individual trolls in this case, but it requires work, and I understand not all moderators want to spend so much time.
