The goal is supposed to be to add users to your network that you trust in order to decentralize the network...
The idea is to add users that
contribute to the trust network, not just users that you trust. If you trust someone, give them a positive rating.
Strange that I'm listed as a clear trust abuser along with someone that is 400% higher than I am in his "artificially increased" rating while Hostfat, Cyrus, & Tomatocage are all within a few % of me or infinitely higher and aren't...
I have no idea why Tomatocage isn't listed as such, however in the case of Cyrus and Hostfat I'd expect it has to do with their low trust score after the fact - as mentioned in the post.
(Huge percentage, but only 4 unique trust)
Someone giving themselves +1 rating, while not necessarily right to do, is less damaging than someone giving themselves +20.
