I reported a guy for trying it on me (I saved the neomails where he said he was going to offer a specific item, and then he switched it for some cheap crap).
I checked the next day and he was frozen. Moral of the story: if the lamer decides to try and scam other people and they report him too, it doesn't matter if you think there is no proof. TNT won't freeze you for false reporting because obviously something is fishy. People do these scams because they think its not reportable....but it is.
Or maybe I just had enough proof (between the neomails, the lot number, and his 3 day old acount....
)
