It seems somehow logical to me that if theymos doesn't allow someone to advertise via banners (like in this case 1xbit), that their signature campaign gets banned too.
To say the least strange decision, because you forbid them to pay the forum to advertise them, but at the same time, you turn your head to the other side and pretend not to see the same people using the forum (completely free) for their advertising. Such actions are not very clear even to us who know the rules of the forum more or less, and it is hard for me to imagine how confused some other members are.
