I doubt that’s true. Linux is barely 2% of the overall gaming market. 4% if you include general desktop users. I do not believe for a second that a tiny fraction of 2% who play roblox are “mostly” cheaters.

What’s more likely is they’re Windows users who are running a VM to circumvent the anticheat, and the Officers are too lazy to pay their devs to come up with a viable anticheat that doesn’t exclude people.
