Reminds me of when I had the full version of Minecraft playable for free on my website and got a C&D over my use of the Minecraft trademark*. The application was legal (essentially hotlinking an applet) but it still caused its fair share of trouble.

I ended up taking it down anyways to appease script kiddies that were DDoSing my site, but not before setting my DNS to the DDoSer's C2 server, resulting in a temporary lull in the attack.

* I have no relation to Team Avolition. They were allegedly illegally rehosting Minecraft. I was just hotlinking resources from sources that were allowed by the Minecraft ToS.
