This was an old screen from 2017 that was activated by downloading a fake copy of the Roblox Launcher, or playing a game that requires you to buy it, but not buying it.
Some more lore for the anti piracy screen: -Only 1 person ever encountered this. He was a hacker, and hacked 10 games that usually cost Robux. The launcher is always monitoring what’s happening in-game, on the menu, and if someone is hacking.
