Most illegal tubes, except the bigger ones, are actively uploading other people's content to their own site. When a DMCA comes in, they comply with the request and remove the offending content, only to throw it back up under a different username.

It then becomes a game of cat and mouse with content providers sending daily DMCA to multiple sites. A lot don't bother.
