I posted it in that thread.

A guy named Zwo hosted it. NO SPOILERS PLZ. I HAVENT PLAYED IT.

Just because the creator of the map isn't the games host, does not mean its stolen.

Zwo's Profile.

He leaked the map that doesn't mean he stole it but leaking is just as bad as Millennium trusted us to not leak it until it's done no matter how tempting it is.

Yeah, even though I was leaked a copy, I didn't leak it anymore

Please don't waste my time to set up a Rickroll map via map attachments.
It isn't funny.
