Would be nice to see something referral based. If you don't like X, block them. If X invited Y and Z and their invites behave poorly, you can block the whole tree. Kinda like lobste.rs referrals but for wider internet

I guess the correlary would be like how you can block an entire ASN if you find a lot of abuse from it, but at the human-network level.

Just peeping Fediverse for a few years i can only imagine how toxic that would get. It would be a constant ideological war.
