Oh, yeah. Twenty-five years ago

, HHN was more like a local haunt where direct interaction was common (if not required). Hellgate Prison - notoriously - had scareactors taunting guests with incredibly vulgar and sexual things (because it was a prison in 2003).
We also had a show director livid at the Catacombs cast because of the Cats & Combs thing because it implicitly rewarded fans and impacted the show for other guests. The direction of houses is very much “same experience for every guest” now. So, yeah, a scareactor fist-bumping a guest in a house could absolutely get someone in trouble.
The final set is the only time that sort of stuff is kinda “acceptable” (within reason), and that’s because the ramifications are somewhat less.
