Wouldn't it be great if we put a limit of 1 feedback left to a person only and not an unlimited feedback which leads no doubtly to big spam being created and a whole mess in forum profiles.
While I agree that this joker should have his spam feedbacks removed, I would argue that sometimes it's appropriate to leave more than one feedback for a person, but usually those feedbacks are left with some sort of gap in between--multiple trades, and the like. I wouldn't want to have it limited to just one, or even have any limit at all. It's pretty obvious when someone is spamming your trust, like this guy is.
Hell, in an ideal world a mod would ban his stupid ass for selling accounts
and spamming negative trust. Unfortunately that probably won't happen. Sometimes you just have to trust that a person will look past all of those garbage feedbacks to see the ones that are relevant to doing bitcoin deals.
