y'all hackers forgot the blue team solutions for the threat model, lol.

if you don't want people putting stickers hither and yon around the facility,

and you know you're gonna have twenty thousand people in cosplay as "a problem",

then in addition to the blessed sticker walls, you deploy some -honeypots- to catch the kids who you -know- are going to be assholes about it,

and you perform some big loud interventions when there's been a population flush in a region to demonstrate this, by having someone "catch" someone "sneaking" a sticker onto the honeypot,

and you make sure your honeypot locations have visible faces on them because you -know- the googly eye thing is constant at this point.
