actually i know of plenty of sites with illegal content - always have. i email the content owners when there's a watermark or when i recognize the content. when the site is one i'm being asked to review, i also email the review site owners to let them know.

over the years, i've seen a lot of stolen content that was resold. once i even licensed a stolen set from a thief that created his own content site. and i know of 2 producers who found their cotent listed on PPV sites under other producers' studios.
