I just want to say if merit system is introduced and participants are required to have certain amount before qualifying, this will prevent many good members not to participate and ofcourse the campaign will be in the hands of the privilege few whom from my observation are already in all other paid btc campaigns,
If your posts are good (hence, you're a 'good member'), then merit should not be your problem. I'm pretty sure 5 or 10 merits is enough to filter out most spammers no need to make it 100 unless you want a high-quality poster.
I guess the idea of yobit making this campaign open was to have as much participants as possible spreading the advert of cryptotalk all around the forum, and I don't see why posting in some thread (generic thread according to some members) should be judged, this forum is called bitcointalk which means those thread will be the most visited thread by many,
If you post in threads or boards that are spammed, then nobody would visit that board except spammers. I'm pretty sure even Yobit doesn't want to advertise their website to a spammer.
Maybe they should have thought it through contemplating all eventualities including abuse of the system by flooding/spamming before they launched the campaign so they would not have to face it at a later stage.
Yobit has a long history with spam, pretty sure they wouldn't hire yahoo in the first place if they can spam here without any problem.
