As someone who likes earning/unlocking achievements, it is frustrating to hop into a pick-up game where the host has enabled cheats so achievements are unavailable.
Asking hosts if they've enabled cheats or if achievements are disabled isn't reliable, as hosts will either lie or may not even realize that someone they've given moderator/admin privileges did it.
Having the state clearly displayed somewhere, like on the tab/info screen, would be incredibly helpful. Something that clearly says "Achievements unavailable" when they've been disabled, especially something that's visible during the initial respawn when first joining/spectating the server, so you can decide whether to leave or stay, would be important. And, some kind of notification when the achievements are disabled, so you don't have to keep checking to see if they've been disabled while you're busy playing.
