What's going on here? Does Cloudbet hire a bumping shills since there's a lot newbies with copper membership keep replying in this thread. I don't think those copper member-newbie rank accounts are just accidental, not many users are want to pay copper membership and you wouldn't see copper member-newbie rank accounts replying on the other thread except on Cloudbet.
You can't prove it. The best course of action you can do is to report the posts that you think are spam. It takes only few clicks.
