That's the bitter truth. Many sites could not do well to be in position to pay the users and turned to be a scam. It is understandable thst they can pay the users only if they make profit. But what hurts and annoys the users is their lack of communication. They don't convey the right message at right time. They can always be professional and raise a red flag when they sense that it's not working..most of them will not do that.The site needs to earn to be able to pay the users but the problem with forums is they cannot earn enough, so they end up becoming scam.
