Why majority of the post here is about merits?? I know that this category discusses about the forum but ALMOST the topics posted is about merits. Is this now the merit discussion?
Because it's a very new system and people are both confused and annoyed by it. You could say the same thing about ranks/activity and there was plenty of crying from users here when the signature restrictions were first implemented. People will get over it. I really can't wait for the hysterical crying if signature campaigns ever get banned. Can you imagine in?

taxes are making up 45% of my country's income. people are posting here with 5-50 accounts as full time job. they don't care if what they're doing could put them out of their jobs.
I see quite a few people from the Philippines and Indonesia claim bitcoin is good because they don't have to pay taxes on it (lol) and it just goes to show you both the ignorance and naivety of a lot of them but they're in for a shock when the government comes knocking on the door when they find out the level of evasion that is going on via this board and other bitcoin avenues. Good luck when they try go get a house or car or any other substantial purchase and they finally have to explain where all this untaxed money came from.
Removing signature globally will kill this forum from having visitors. We all know that having signature campaign is the one the brings traffic to this forum unlike other crypto relative forum. Without enough traffic advertiser wont waste money to put ads here which is necessary to pay all the bills for maintaining the forum.
No it wouldn't despite how much you want to believe this and theymos has already stated that if the Merit system doesn't work then disabling signatures would likely be the next step. It would kill shitposters for sure as they would disappear en mass like a fart in the wind but this forum was fine before signature campaigns were here as are all the other forums on the net that don't have campaigns which is 99.999999 of them. People would still advertise here and the forum would likely take in even more money because the majority of advertising money is lost to signature campaigns already.
