If you count winners by the rules. Then DomainMagnat is first. His member have 30 posts . Anyway I did not participated in the contest, I put that link on my Sulumits Retsamew, so you can disregard my price, my members dont have over 10 posts. So I can not accept the price. Sorry.
BTW now it is clear why I attacked one of this referred members yesterday. Since I knowed that they got paid to make 10 posts, googling their names together was resulted an easy spot.
