I've noticed a few paid to post forums where you can post on any section of the forum and you will earn a few points. Once you have earned a certain amount of posts, you can redeem it for cash via PayPal or some other sort of reward. The sole purpose of these forums are for members to earn cash. I presume the administrators make money via advertisements. But do you think as a webmaster these type of forums work? A lot of these forums can tend to attract a lot of spam and low quality content. Are they worth the effort and initial investment?
