Dumped a bunch of API files and the Rockstar launcher into the root of my games folder, which then revoked write privileges on every file in every subfolder, presumably as some sort of anti-cheat. It then proceeded to break several programs in the games folder because they couldn't actually write any data without being run as admin. I spent a few days wondering why so many of my programs were suddenly breaking, and thought I was staring down the barrel of a hard drive failure. No, it was just Rockstar Social Club and the accumulated ~150mb of files that didn't get deleted after I uninstalled. Had to manually clean everything up and reset permissions myself.

Would still be fucking boring even if it wasn't malware.
