Scams wouldn't exist without greddy idiots and con artists wouldn't be artist if people showed them no attention.
The forum is full of scammers and the moderation is non existant and the worst is, they are advertising for this site... RS is just the biggest scammer among them.
Please don't blame people who tend to trust others, and I don't think buying some share of an exchange is something greedy. It's the scammer who has to be blamed.
Trusting someone over the internet is the among the worst mistakes you can make. Especially someone with as colored a history as RS.
