I'm sometimes thinking about account verification that requires work/effort over time, could be something fun even, so that it becomes a lot harder to verify a whole army of them. We don't need identification per se, just being human and (somewhat) unique.

See also my other comment on the same parent wrt network of trust. That could perhaps vet out spammers and trolls. On one and it seems far fetched and a quite underdeveloped idea, on the other hand, social interaction (including discussions like these) as we know it is in serious danger.
