Is it normal for feature porn dancers to get this nasty live on stage?

This club is Paradise Showgirls in Southern California.

Nautica Thorn was basically getting eaten out by a "customer" in one of the pics. It is the 13th pic down.

Cherokee literally sat on a guys' face and looked like she was smoothering him with her cookie.

See for yourself, click on the link and then click on a porn stars' pic to see multiple live on stage pics.

I'm well aware of what some of these feature porn dancers do behind closed doors (i.e. escort). I read TER quite often.

What I'm mildly surprised is flaunting it (i.e. oral w/ customer) in public view. This is just asking for law enforcement trouble. Especially in So Cal.
