I've noticed several users request reasons for cold votes and a whole host of threads about cold votes. But the whole reason, some of us do not gie/want to give feedback for cold votes, is that you get shot down!
I remember giving a mod a cold vote a while back, and the next thing I know my accounts suspended for giving cold votes. If a deal is not a deal or its rubbish/***** then it should be voted cold. If its a hot deal, it should be voted hot.
It's annoying seeing others who give feedback get shot down. Hence feedback reluctance. If there is punsihment then there will be a reluctance to vote never mind post deals.
