OWNR requires users to make seven posts in the Alternate cryptocurrencies section - most others require posts in the Games/Games discussion sections.
Does it matter? As far I see, OP is an overview of Bitcointalk Signature-Ad Campaigns which pays in BTC. IMO, Gambling section is no better than Alternate cryptocurrencies section.
Another thread that popped up recently requires users to start and maintain threads each and every week - not sure how that one went.
Are you referring to
this? They seem to be active for 2 weeks with 3 campaigners and
paying them as promised.
