I was left 13 feedback by this joker. 2 positive and 11 negative. I've shown Pooksie the e-mails, and asked him to fix my feedback and look into Vendacious's alt accounts. Thanks for all the positive support guys, means the world to me.
I agree with twiztd, sucks that I'm out $20, but if it gets him IP banned and prevents others from losing even more than that, it's more than worth it.
I've done maybe 6 transactions on here, only a couple got feedback exchanged, but it's always been pleasant. Thanks to each and every one of you who has replied to this thread, and double-thanks to Twiztd and Rozz for going to bat for me.
Rozz, would you mind PM'ing a mod about the fake feedback/alternate accounts debacle as well?
