It think this will only work as long as the number of spammers is low. At some point we need to have a default filter by web of trust. Anon npubs will be noise then.

You are not wrong. But you can still do this now if you want, but it takes 5 steps to do it.
Wondering if there is a way to use the blind signatures from ecash to attach trust to an anonymous npub. You could vouch for that new npub but it should not be possible to see who vouched for it. Have no idea if that is feasible.
It does seem to be a very spammer friendly feature π and I think Iβve heard of some spammers basically doing this already
doesnβt mean itβs not a good idea anyway
