If there was any feature in this forum like OP preventing a certain forum member from posting in a thread, then it would have become difficult for people to warn about the scam. @CryptopreneurBrainboss post would probably be deleted by the topic creator soon. On top of that since scams aren't moderated there would be no point in reporting the thread too. So the only possible way to prevent the people from participating in the campaign is to PM each and every member who have applied for that.


As nutildah pointed out, Hhampuz trade with Livecoin went smooth and so was the positive feedback. The trust ratings are opinions of a member with another member. If I was in the same case, I would have left a postive feedback since the deal between me(campaign manager) and the campaign owner was smooth and successful. The positive trust rating given by Hhampuz is no way related to the scam accusation risen against the exchange and certainly it's good to leave the feedback.
