@rysiek @pearlbear do you have an idea beyond closed registrations for detecting & handling spam? Because these attacks are constantly evolving, and a lot of people are working hard to fight back the attacks & fix federations to propagate suspensions quicker too — defederating can't be the answer because then the attacks will just move to other instances.
@thisismissem let's start with closed registrations on the biggest instance out there, which happened to be the source of three major spam attacks over the last 10 days.
I'd like to see a fedi where the biggest instance is no larger than 5% of the active accounts; m.s currently is at ~13%. That's simply dangerous.
Defederation is not the solution, but it is sometimes necessary with badly moderated instances.
