UK WoW players don’t allow to pay WoW through British bank

UK bank Halifax make a big decision which affect UK World of World fans with effectively that ban all automatic payments to the game developer, owing to a "a significant number of fraudulent transactions through Blizzard's gaming sites". The bank claims that this in no way reflects on Blizzard, but instead on players who are using stolen credit card information to pay for World of WarCraft accounts. So the bank will ban the payments according to The Register.

"We have...blocked the majority of Visa/Mastercard transactions we receive from there in order to combat this. We do not believe the fraud is anything to do with Blizzard themselves, their sites or the integrity of their billing systems, rather it is site users utilising stolen credit card details to pay for subscriptions," a Halifax representative explained. The rep went on to point out that "if a customer does want to subscribe to a game site operated by Blizzard, using a Halifax or Bank of Scotland credit card, we can arrange for the payments to be processed for them if they contact us."

The bank didn't reveal what exactly "a significant number of fraudulent transactions" means, but if it is as rampant as it claims, this seems to be a logical move. But if it is that bad, how come we haven't heard of other banks making similar decisions?
