Yes, most members don't care because they only care about the signature campaign they are involved in. Maybe if there were no signature campaigns then the forum would be clean and the ones who would survive would be members who like to discuss. So the best way to deal with buying and selling accounts, spammers, scammers, and trollers, is to remove signature and bounty campaigns. 
This is something that was discussed a lot, but we all know that without sig campaigns this forum would look completely different and it would probably lose a lot of members. It is an extreme measure, but it should also be emphasized that it is one of the measures on the table in case nothing else can help.
I used to ask for a signature holiday 1 month a year any month pick it and do it lets see how much traffic leaves the website.
I now realize theymos is far more of a smart business man then I have ever been.
the traffic and coins earned via the signature campaigns are a world wide advertisement for BTC as a business tool.
I belong to a campaign now I do not do a lot of campaigns but with my mining income down I wanted more income. So I got into a campaign.
This campaign has given away 20 btc in 50 weeks and has made 10s of thousands of posts people are earning and spending the BTC. So I am no longer in favor of my 1 month a year campaign vacation.
Not that I want crappy spammy posts. Not that I want people that have alts stealing signature money. But the brilliance of allowing signature space rentals is quite a good idea.
