Oh but it does have a positive effect, you can bet that he, and others who find out about this, won't slack off when it comes to doing their due diligence.
It does not. Your emotional argument against OP is your own thing that is not of concern of me. Based on past ways of settling similar situations, Marlboroza should remove his rating or someone should counter it.
I don't have any personal problems with the OP. I am just sick of all the scams around here and would like to combat that as much as possible. What's "your concern" is totally irrelevant to this topic, the user received red trust for organizing bounty campaigns for scam projects multiple times and I don't see why you are so actively combating that. Marlboroza did what he thought was right, I agree with what he did, while you may not and that's your opinion.
