I've had some names taken by a registrar.
Also, I had a massive problem with PayPal. I sold a name and the buyer paid using PayPal. It seems that he had got the money by selling to a guy who PP decided had breached their terms. I had a cleared funds account, so PP shouldn't have transferred the money if there was any doubt, but it seems there is a six month wait for payment confirmation with PayPal. You only have a loan until then. Fortunately, I had moved the money out immediately, and I had used a card that only had 7 days life left to open the account. PP chased me for about 5 years for the money, but refused to go to court over it. This is why I think PayPal is a dishonest organisation, and I fail to understand why people continue to use it. There are so many reports of problems and losses through their actions.
