Eh, it comes down to this:
If it's truly non-consensual, then that was probably not the best idea they've ever had. You get sued pretty fast for that kind of shit, and I'm honestly surprised that Miranda DIDN'T drop the hammer on them. I guess they just got lucky that she's a good sport.
If it's NOT non-consensual, which is the most likely thing, then they're using false advertisement to sell their videos and should be sued ANYway.
All in all, it comes down to the acting level and how far a company is willing to go. Obviously, a company dedicated to rape-bondage won't ACTUALLY kidnap someone, rape them and then sell it stating that it's "100% non-consensual"... however, I guess companies like TP think that it's different when it comes down to tickling.
As for my opinion? I agree with you guys - it's fine to push someone to their limits, and it's even fine to do SOME non-consensual aspect to it, but when you just won't stop you're just being a total jackass and, frankly, could get in HUGE trouble. The whole reason I'm INTO tickling/bondage is because of the fact that whipping and stuff is somewhat hot, sure, but it really doesn't do it for me - I prefer the lighter stuff, hence this. When it's TOO non-consensual... eh. It's just not fun anymore.
It's that reasoning that I can't read the "Ticklish Nerd" story series everyone claims is the best one in the TMF. Even THAT, though fiction, is too harsh for my tastes...
