Isn't really the whole basis of 'Super Heroes' being 'world breaking' in many situations?
And sure, you can't baby sit players all the time, or check logs, or make it very and abundantly clear during character generation that these are the expectations for players on the game. I mean, really, there are definitive steps that staff can take to mitigate the situations. Then deal with those who won't respect the expectations and leave the rest alone.
Have your rules. Have your expectations of what you want players to be able to do in the world. Let them know they need to fit in that structure. You know, how a good GM has a set of table rules printed up and set out for the players so they know what their expectations are?
And if Staff can't monitor the expectations on their game, then what are they staffing for?
