because of a loophole in the law probably. if you provide a link to a third party website, that third party is responsible for everything. you are a mere messenger. you could still maybe get in trouble though. if you post a direct download link to an album you are the leaker, and mike can be held accountable as the owner of this website for not removing the link. maybe he didn't intentionally leave the link but just missed it. basically, it would bring a stress on him that he wouldn't need.
these are all assumptions by the way.
