It’s very unlikely that they will region lock. Wildcard is owned by Snail Games, which is a Chinese company. I would assume that Grapeshot is also affiliated with them.
They could/should do something about the aim botting/exploiting though. There’s been talk all over the forums/discord that they are duping and that’s how they have so many galleons/large ships. Though if they ban them, they will most likely just make new accounts/purchase the game again. Really frustrating.
