you could try to cook up some kind of trust chain, without totally abandoning privacy.

Get a government-certified agencies minting master key tied to your id. You only get one, with trust rating tied to it.

With that master key you can generate infinite amount of sub-ids that dont identify you but show your trust rating(fuzzed).

Have a cross-network reporting system that can lower that rating for abuses like botting.

idk Im just spitballing
