Well you can believe that all you want, it's simply not true. MFC does not give out anyone's IP address to anyone.
The only way to "track" who is tipping anon is for the model to watch a member's total tip amount. They do have access to several different sources of data for tips received. While tipping anon does hide who is tipping, it does not keep the tip from going on the member's total tip amount that they have tipped the model.
In other words, if the model sees that a member has previously tipped her 100 tokens, then gets an anon tip for 10, then looks at the member's total tips and can see the total is now 110, bingo, u have your anon tipper. It's not rocket science but it does take time to go thru all the possible tippers. If she is persistent or has a good idea of who it is, it can be done.
I'm not saying I know everything but I have been around MFC for a long time and have many friends on both sides of the screen. Thru these conversations over the years, I have a pretty good grasp on how things work on the site. With that said, no one knows why your model friend would tell you what she told you or what her motivation was/is. All I can tell you is that the things she told you do not match with reality.
I would also add a word of caution with regards to using a VPN. I know for a fact that MFC frowns on these and has banned members for using them in the past. It doesn't matter if you are a long time member that has put lots of money into the site or a newb that just joined last week, you will get it.
Also, (I hate to keep bustin your balls, but you are just wrong man) your logic for multiple accounts is flawed as well. From what I gather from your story, the WK signs off and then signs in on another account to tip anon? This just makes no sense whatsoever. If he is going to tip anon, why bother changing accounts? Are u telling me that he knows the methodology that I explained earlier and he doesn't want her to know it's him? Most WK's I see want the model to know about every single token given. It's not like them to hide their "love". The whole scenario is enuff to give someone a headache. The dude is a wak job and the model doesn't care because thru all the crazy talk, smoke and mirrors, at the end of the day, she is getting tipped. That's what it all boils down to.
But when some idiot like him puts "Not for count" in their tip note, I'm done with tipping. That tells me that the model wants everyone else in the room to tip for whatever the goal is but her "regulars" tips are special and don't need to participate in the objective of the night. If they want to tip something "special", tip it ninja.
The only reason I have seen in the past for people to have multiple accounts is to act like a troll, cap or some other natharius actions. I've had one account for over seven years now and have no need for a second account because I don't act like an ass and don't have anything to hide from the girls or the management of MFC. I wish members and models would both be held responsible for their actions, then a lot of this unwanted drama would be stopped.
My apologies for this being long, I got on a roll, haha.
