Do you want an example? Ok…try this one (i post the links only as an example, obliviously you can remove it):
In Italy i can’t reach http://www.europacasino.com because all the local internet providers have the obbligation to block it, I only can see a white spot where is written that this site is illegal. Otherwise I’m able to reach http://www.europeitalia.com without problems and all my linking codes (even the oldest) are redirecting on that site when the geo targeting determine that the visit is from Italy. I take the example of Casino PArtners because this group have the highest presence in Italy and they didn’t lost it at all since 10 months from the law, I only want to understand the Credit Card potential problems for USA, maybe this should be a bigger problem.
