Even the sites heavily focused on customer service an interaction - like amateur sites - can get hit *hard* by an asshole who knows he can chargeback.
One lady on amateurmasters had a member who came to her site almost daily, was present and in chat for *every* webcam show, she thought he was a fantastic member.
After 8 months he charged ALL 8 months back at once.
She never got the opportunity to show the logs, show the IP addies or emails or chat logs... nothing. He told Visa to charge it back and they did.
Running a tight ship and fawning all over your customers isn't always enough - the customers have learned that they can legally commit fraud through Visa and that's all they need to know.
