You may know the Roblox game, Welcome to Bloxburg. It’s a game where you can build a house and work. You can deliver pizza, make pizza, etc. Most players, though, use the game to build.
The players who get attached to Bloxburg play it again and again, and may even spend money on Bloxburg cash and gamepasses. The game itself costs Robux, because it is still in beta, even after years of being in beta with no big changes or fixes.
But as it turns out, the Bloxburg team knows YOUR address. Every time you create a new house, more information about you is stored in the Bloxburg system. They take all this information and use it to find your address.
If you still play Bloxburg, STOP playing! And move, because Bloxburg probably already knows your address.
