Just to prove the OP's point, I had some money deducted from my FT earnings this month. No one has bothered to inform me why. Hadn't I checked, I would never have found out.

It was probably from a fraudulent credit card.  I heard they are having a lot of that going on there (I closed my account there so I wouldnt personally know though).  This may sound silly, I know, but I am surprised someone (contributor in USA) has not turned them into the BBB or Federal Trade Commission.  From everything I have read, the company that accepted the fraudulent credit card is the one that is supposed to take the loss and if the credit card company is not able to get the money back from the retailer, then they take the hit.  Of course, if a retailer has too many fraudulent sales, they will get fines from the credit card company and possibly loss their ability to accept credit cards.
