You can claim about it all you like, but people will use cred in sub-optimal ways.

People use everything in sub-optimal ways. That's what makes them people.

Earlier today, I was thinking about the possibility of inverse cred -- e.g., the fewer people have granted Alice 'troll' cred, the more Bob's 'troll' rating would go up if Alice gives 'troll' cred to Bob. Of course, this would be subject to the same diffusion effects as reciprocal cred. Metacred, then...

We can put mechanisms in place to punish people who use cred in suboptimal ways. Probably this would involve temporarily invalidating someone's score until they fixed the problem.

A kind of 'cred police'
