It's can be done with downloadable games to share viruses. I saw some cases when original dev's need defending self again enraged players who blame him for blocked PC...
I think it's too more worse case than just a piracy/steal-copyright. But some times devs can do strange things with game hosting, and i prefer to inform well-known dev and confirm incident before warn moderators. (For last two-months i saw three similar episodes with books and 1/3 has been a just another author account on fan-fiction site)
