Inquire over the phone with her agency

You confirm this by speaking with Crystal herself (after a few screening calls).

"Hi, baby, yes, it's me. I'm sooooo happy you're willing to fuck my face on stream this Friday. Yeah, don't worry: the rougher, the better. My agent will have us both sign a liability waiver, so get as freaky as you want. You've watched my shows, right? You know I've got, like, zero gag reflex!"

So, this happens to you. You're just an ordinary dude, but, for some reason or another, you're a magnet for masochists, sick-in-the-head sluts who want to push their limits and bring out their fucked-up fantasies. Goon girls who are turning into the awful pornography they consume religiously. Freaky, rough, physical fucking. Degrading, humiliating sex acts. Immoral and deplorable degradation.

"Honestly, I'll probably be diddling myself while we shoot. Yeah, it's so hot getting exposed in front of an audience. And I like it if you spit on me and slap me around." Camgirls thrive off of disgusting taboo violations, setting the bar for teen girls to imitate them.
