EXACT SAME THING HAPPENED TO ME!
I posted a thread wanting to exchange PayPal for Paxum and he contacted me via PM. He showed me via Skype video chat that he has the funds in Paxum and then asked I used the "friends and family" feature so he didnt have to pay any fees. Once the funds were sent, he confirmed receipt and said I had to wait until he was able to withdraw it or I could get an immediate refund (He didnt say I would have to wait upfront, I thought it was going to be a quick transaction) so I asked for a refund, he said "One minute please" then blocked me from Skype and off he went.
Sadly it appears he was using a new BHW account, new PayPal and new Skype so likely he is reading this from his new ID laughing at us. I have a fraud dispute open with PayPal but Im 95% positive he is churning and burning those accounts too.
