Buying gold through player auctions?

Hey guys, it's been a really long time since I've done anything black market related, the last time being... Late '07 to mid '08 xD

Anywho, I've been contemplating on buying gold through PA via credit card but I was wondering, what are the chances of getting banned for RWT, and also, of getting scammed?
In the same breath, what could I do to avoid getting scammed and/or banned?

Muchos thanks

 

Just buy at a trusted seller on PA and you should be fine, some of them have special RWT methods. R2Pleasent uses these to i think
