The forum trust stuff has largely replaced the scammer tag.
I've gone ahead and and put in a negative rating for Cypherdoc, Simon Barber, and Hashfast itself.
Am I missing any other parties which acted as agents for hashfast and concretely promoted the belief that if hashfast failed to deliver they would refund the full amount paid?
