Escrow.com question

[randomo]

Hi,

I'm using Escrow.com more often these days, to avoid the scams that are going around.

Question: What if someone pays Escrow.com and they approve the payment, but then it turns out that it was fraudulent (a stolen credit card number, for example)? Who loses the money - you or Escrow.com?

(Followup question: is any escrow service more secure than any other? For example, is there any reason to prefer, say, Sedo's or Moniker's escrow services, rather than Escrow.com?)

Thanks.
