If you bought a car that turned out to be stolen, you might wake up one day to find it's gone because the police recovered it for the owner. It's similar here - buyers looking for a bargain that might be illegal are part of the problem of IP theft. They can seek recourse through the seller they got it from, and if that doesn't work, they shouldn't have trusted a dodgy overseas black market seller with their money.
