I was trying to find what restrictions, if any, does MFC have on advertising a model's presence or offers on third party websites? As I understand it MFC is more liberal on this issue than just about any other site. The MFC Rules & Guidelines page seems to remain silent on this issue, and the one section at the bottom that talks about gifting models says "Members are free to exchange address information and to send the models whatever they like. But of course we cannot offer any support for transactions that take place outside of our site." The attitude this conveys in general is that they tolerate off-site transactions, but they will not be responsible for them. That's more than reasonable.
To give a specific example, could a model's MFC tip menu have prices for fixed price ticket shows, where the show is conducted offsite, either Skype or CB CrazyTicket? In that case the tip menu on MFC would be mentioning MFC's competitor by name and telling the user they need an account on CB's system in order to get the show. I would hate to find out later that MFC actually forbids that and has the rule hidden away on another rules page.
