Be careful when you buy or exchange PS money or Skrill/Neteller. There is always a chance that the money has come from a stolen credit card and the PS money will be reverted back to the original owner and your account will be blocked until further verification. I know this from personal experience. So, Be careful. Check when the money was put into the account. More than a month would be awesome and suggest that the money is clean. Also, Dont forget to use escrow.
