Faking in tickling videos

I would say it's the same as with fictional and nonfiction movies. When we see a nice movie we don't say the actors are faking. They can only fake too much in acting that we may notice.
We say they are acting, good or bad.
That's what I start thinking of some models.
If using this concept, in my opinion Tickle Abuse is a great fictional tickling company. It's not hard to see when some models are acting. But what impresses me most is that customers keep watching clips with models who are obviously acting. I'm talking about blond Scarlet for example.
So this leads to an interesting question - is acting (or faking as you call it) always a bad thing?

Tickle Therapy is purely nonfictional tickling company as we don't even see the reason why tickle therapy patients should be faking. In fact sometimes we ask them to try to pretend they are not ticklish, which is a mission impossible for them
However, now I really can't blame fictional tickling because so many custimers seem to enjoy watching it.

P.S. Please don't get me wrong. There were many models in TA who were really ticklish and were not acting. Many great real tickling clips.
