I’ve dealt with similar enough issues in my web publishing time. For me it was a case of people selling photos they didn’t have the full rights to sell (such as a fashion photographer not having signed the proper model release form with the photograph’s subject). After a few structural changes, all copyright hits and infringements stopped. To achieve this I registered a company in the Seychelles to own and publish the site. Few people are interested in finding a lawyer to sue you there. If I were to consider other countries at this time, I’d presently look at Seychelles, Moldova (the authorities have 0 interest in enforcing copyright claims there), or similarly unattractive countries where the cost of finding a lawyer simply outweighs the benefits of suing someone.
