The OP and some of people in this thread were suggesting negative feedback bombing people who sell acounts or who are involved in any way that is what i was referring to. I would suggest if that ends up happening to first warn people first for a while - "stop selling accounts or else etc" if newbie account it doesn't mean anything, might aswell negative feedback bomb.
Okay, that makes more sense. I initially though you were referring to banning account sales and/or removing signature campaigns/signatures. If you are banning account sales and its an official forum decision then yeah discussion is over, you just delete topic, everyone has to agree 
While technically true, I doubt theymos would make such a radical change if everyone is against it.If you ban signature campaigns then account sales will probably drop to almost nothing but forum activty also drops, does that matter? i dont know.
Quality over quantity. I'd rather have 10 useful posts a day, than 1 000 useless ones.
