To the three posters above:
selling an account, which then gets suspended specifically because of the transaction, and refusing to refund the account constitutes as a scam. I don't know if you guys are crackpots or just dumb but it doesn't take a rocket scientist to figure this out.
You're encouraging trust feedback abuses by this kind of dubious justifications. I hope you're not doing that yourself

It's a fraudulent hijacking of the trust feedback system.
Wrong. Tagging high-risk people before they are able to scam is an appropriate use of the trust system.
I agree with you but you must provide solid elements for that and not tagging people with 0 explanations like here, moreover what you are saying here is your opinion on the case, until now I understand he has tagged him for scamming Amazon.
Think of it another way if you saw a high yield investment program with stupidly high return rates, it's appropriate to tag them before they are able to steal people's money.
Where have you seen that please? Every economists call Bitcoin a ponzi and a pump and dump scheme, you're willing to tag all users here?

An HYIP would only be a scam if it presents itself as a safe investment. There is even a section for them :
Gambling
Gambling and all "investments" that are so risky they might as well be gambling (HYIPs, pyramid schemes, etc.)
