Yeah, you were scammed :?
It sucks, but you just have to apply a little bit of logic to the situation at hand when these things are presented to you (and as a cam girl, I get the impression they'll be presented to you often). Just ask the question "why?"...
Why is this "offer" being offered to you in the first place? Has it been offered to other girls? Or just you?
Why do you have to "perform" to be eligible for it? Surely you're either eligible or you're not, ya know?
Why are you being asked questions? Surely MFC already have all the details they need from you from when you signed up.
Is the person offering you this "premium" status an MFC representative? Can they prove it? Do they back off when asked to prove it?
Why would "MFC" offer you these "benefits"? What would be in it for them? Does any of it make sense as a business proposition?
Is any of this "premium model" business mentioned in the contract you signed or the MFC wiki?
If any of these questions (or the many others that arise from the shady proposition as you've described it) throw up cause for doubt or concern (and all of them should) then steer well clear of it, yo :twocents-02cents:
