I mean, can we really stop scammer from doing their actions, instead of just to make an allegations and burst them? Like, we don't give any chance for scammer to be exist here, and make this forum completely clean.
No. Scam is not moderated.
I am sure they are working on new scam which they will announce somewhere in this forum, it is what they do for a living. So how to clean forum from scams? You can't, at least we can weed out some scams like this one.
