ArcadeProz offsite scamming possibly?

Earlier I seen this user-
http://sythe.org/member.php?u=350549

and in his sig, he had a link to his website, so I decided to google it and found another forum with info on arcade games that he posted on. Turns out he scammed someone on that website. Link-

There is not proof on there, but there is a moderator posting and saying that he did do it.

Don't even know if you can do anything about this, just dont want anyone getting scammed.

 

Not enough proof
