Oh, sue the fucker as soon as possible for damages. Do not delay. Even if you have not read the interior, just the cover and blurb are enough to sue. What a cheeky bastard.

I had it once on Medium, again some unknown female. It got taken down immediately once Medium became involved.

I also had it once with YouTube when some jumped-up teenage schoolgirl posted my song and production as her own and refused to take it down. I contacted YouTube and threatened to sue them for five million dollars. It came down.
