FRG TeamFanShop was a testing ground for identity thieves to try out credit card data they had stolen. The site is not active as of 2015.
Most commonly, a $5 charge was billed and then immediately refunded to prove the card was valid. If it was, the hackers proceeded to use the card on purchases from reputable companies. Occasionally the hackers would begin with a more expensive charge from FRG TeamFanShop and work upward from there. Eventually, credit fraud victims would be out hundreds of dollars as a result of the scam.
Fanatics.com is sometimes associated with FRG TeamFanShop. However, the two companies have nothing in common, with the former a reputable retailer of officially licensed sports apparel.
