I mean if I caught a staffer spying on players on a game I was headstaff on, they would be shown the door. Just because someone CAN does not mean they should, and if they do they shouldn't be running a game.
Yes you should be prepared and careful about your DATA and MU's are def not the most secure things by a large margin but these arguments are super weird.
No, your game won't improve if you go traipsing around invisible spying on peoples private RP, Sure staffers have that power, but that doesn't mean they fucking should, now should players 'just accept it' Fuck that. This is about ethics of MUing not the ability to do whatever they want so you shouldnt have any expectation of privacy, You absolutely should, and these arguments about 'oh you are naive if you think you are private' sounds a lot like defending bad actors.
