Had been director at few cam sites for past 8 years and seen so much different stuff, I have no idea where to start from.. or even what's trange anymore.
I would consider not strange enough those who ask the girl to do shower or bath-tub, or to pee in a glass and stuff like that, this is mainstream.
I disagree with the guy who said 95% of private it is sex, that's not true for privates longer than 10 mins really. I seen some guys taking a russian girl to learn russian language, she (clothed) will teach him russian, for just $3 a minute.
From an admin point of view, those strange customers requests make the work more complicated... as you don't figure easily if the model is doing a fetish or she is simply lazy.
For example, some guys wants to see the girl sleep (clothed)... and I mean sleep for real and even for one hour (60+ minutes)... now if an admin browse streams and see a fallen asleep model in private, is that to be fined or no?
Also consider when private it ends the model continues to sleep at times, leaving the chat open after the guy exited LOL
I asked and it seems in a few cases, the girl it looks "too tired" or "worked too much" so the guys who love her, take her in private to allow her to sleep - in other cases it must be simply a fetish.
Some obvious fetishes you can see it is the guy who ask the girl to slap herself in face, that's quite odd to see, especially if she's not that good drama actress, scene looks laughable I think? On the opposite, some guy wants the girl (clothed) to say to the guy all the time: "you are a loser, your cock is small, you are pure trash, you do not deserve I get naked for you, give me all your money", and humiliations like that all the time, again an admin may see the girl to be so mean with a guy, you wonder a little is that ok?
Especially as I seen this being made at a $25 to $50 per minute price too, which is further humiliating for the guy (had to setup those prices per minutes on request, I was amazed myself but well... you always learn something).
There is also the price fetish: we allow the models to set price per minute up to $100 per minute - while the $50 it was "popular" enough by wallet fetish guys (pity they're not so many), the $100 it was used one time only by someone I think was a bank owner or CEO who wanted to talk about literature with some russian girl (clothed) and he had 20 minutes only on fridays (busy oligarchs...), he wanted give $2000 each meeting not to be cheap, but not as a tip, so $100x20 mins = $2000 it made it, he done it a few friday's for a few months, then they must have disagreed on some book author and they stopped. The affiliate was the model herself (she "stole" it from other site, bad of her) so she got most of this fortune.
There are fetishes about the girl to watch the guy's cam: most common it is the man is wearing woman clothes, changing bra's and stockings and she should comment on that (she is clothed again - most fetishes does not require nudity or sex it seems). Admins rarely watch the cam stream of the guy so we may have missed guys wearing yogi bear costumes or things like that
Some fetishes are so strange that maybe are unique ebough so to report these there may be not so professional as exposing private chats of customers. Like that chicken leg hanging thing someone talked about I think that's 1 guy only asking that
