Well obviously I can't put an exact figure on the percentage of people that would leave and can only guesstimate but just look at how many people have signatures on the forum and especially in all those shit threads. Do you think they would be there if they weren't getting paid to post? Ban campaigns and you remove their incentive for posting and the people who are only posting to get paid would leave as they likely have no reason to waste time here so in that respect it would be a good thing. Bad for traffic to the site but certainly good for content. With that being said, there's also probably a lot of 'great' posters that would probably eventually leave too or the amount of time they spend here would decrease significantly over time. I'm all for trying to improve the post quality and discussions but at the same time a dead forum would also be pretty boring. It's just gonna be be a shame to all the quality posters though who just appreciate being able to get a little bitcoin for something they would do anyway and unfortunately it's gonna be the shitters that spoil it for everyone else.
