Scambusting itself is becoming a form of trust farming (not just by Quickseller). Steamroll over a bunch of people, pretend you stopped a bunch of scammers, collect positive ratings, and abuse trusted position even more. This is one of the main reasons I have argued so heavily against "scambusting" in general. People who are wronged will bring it to light, we don't need internet precrime police running around everywhere interfering with what would otherwise be voluntary transactions in most cases.
