Not that I am doubting theophile, but seriously: if he was THAT bad he would of had his E--Y account pulled; moreover, if someone sells something for $6000 and it is fraud it is no longer small claims court but fraud that could include time. And Paypal is very generous with the buyer protection.
Not that I am going to go out and prove it but real scammers get noticed by more than just people on a topic-specific forum. Moreover, to set up a new account would have to mean a new address, name etc... especially to set up a new Paypal account.
A good way to gauge it is to note he offers "buy it now" which means unless the items are bought outright he will relist them. I am going to watch them and see how many get bought then relisted.
But for what it is worth, please note that a Canadian seller, Vlad20000 does the same thing (post lots of gear with nearly identical pictures) which makes sense if you have a business but Vlad is very poor in packaging and shipping, which causes much damage. Moreover, he is indignant about it. Not entirely a scam but dishonest for sure.
