This is why I have the ideas that current merit system is not strictly enough to stop spammers showing their shit in the forum.
Of course it's not enough--that's obvious, because we still have a spam problem.
I don't think the solution is going to come from any tweaks to the merit system at all. It's going to have to be some rules imposed on bounty managers and/or ICO devs who want to use bitcointalk to advertise their shitty scam projects.
