To be fair, I don’t know where world is hosted by at least according to my local law here they’d be right: linking to piracy can get you in trouble.
Now usually you can safely ignore this still, sure. Unless you’re large. And with world being so big I could see them being the very first target someone would drag in front of a court if they are in a place where such laws exist. It sounds stupid, but I can understand why the devs would not want to go through that.
