As I understand it, at its current size, mastodon.social is the largest server.
Current rate of growth of Mastodon, but now it's all on social. Seems like those are big numbers to stay on top of.
Can they keep up with the moderation? They seem to be struggling now, but maybe that's just my perception.
If you tell me, "PJ they'll manage fine." Then I'll believe you. You're far better informed than me but honestly that seems like it's not part of the plan.
