I don't hate any members who are in sig campaigns. I hate spam, period. And yes, it drives me nuts that pretty much all of these shitposters are in bounties or campaigns, because they're getting paid to dilute whatever good posts there are on this forum.

There is a very effective solution for signature spammers, report them to their campaign managers or to mods with help of "Report to moderator" button. The first choice is certainly better, because each decent campaign manager will remove such a user, and maybe even add them to black list.
The Pharmacists have given the right reasons where many signature is haters or anti-spam, junk and low-quality posts. Most of it comes from the bounty altcoin. But to prevent forums from looking bad and dirty, Lucius has provided the right solution. Keeping the forum good is the right thing to do.
