"This is is actually in major violation of EA Games copyright laws. In simple terms, what they mean is that a site cannot not charge money for Sims content that was used by EA tools or free for the person to make. If they ask for donations and don't charge money for the downloads, that's perfectly legal. The staff members are not making the content themselves, so therefore they are running an illegal operation and should be shutdown effective immediately."
