So sorry to hear that.
The thing is, there's scammers on both sides. Although sites try to stop models from scamming so they don't get a bad rep. And it would be sad if she took this out on you, but she could be vindictive and is scamming everyone because she may have been scammed at the very beginning like most models have.
Judging from the story, she sounds like a scammer. There are women who manipulate people (not just men) by making them feel sorry for them. Maybe those things did happen to her, but there's therapy for that. You don't play with people emotions like that to feel better.
Good thing she gave you another insight on the industry but many many many cam models LOVE what they do and are not fake at all. Even if they slip into character, like an alter ego, but not fake, they love it. How else would they become successful? You get figured out real quick because it's so easy to see through the BS.
When someone shows you who they are, believe them.
On the other side, because there's never only one - Honestly, saying you spent $75K on one model you've never seen naked in 14 months sounds too good to be true, even if you're rich. So to some, you would kind of sound like a scammer too.
And if you really did spend that much on the model and her story is true, and you are really eager to meet her in person, she could assume you are part of a sex trafficking rink of some sort, and would be afraid to meet with you. Men do those things to get sex slaves - especially if you're both in different countries - fork out a lot of money and love notes, try to get their address etc. to lure them in, get them to where you are, and then drug them. But I watch a lot of "Law & Order: SVU" so I'm a bit on the paranoid side.
What I do know is that when ever a guy offers a crazy amount of money to be my "sugar daddy" or meet up or whatever, I see red flags.
If you're still holding on, ask her if she trusts you. Maybe you guys can meet halfway somewhere (not her country or yours) in public first so you can prove to her that you really are not dangerous. Her trust in men can be extremely low being that she was raped.
Check out goabroad.com or any other place where there are tour guided trips in let's say maybe Spain (or wherever, just not your home place and not hers), and you both book the same trip. That way, there will be a crowd of people around you and interacting with the both of you. Both of you would feel safe, and you guys still get to meet in person like she promised. (But make her buy her own way, so you know it's not another scam, and if she doesn't show, you'll still have a fun trip and might even meet somewhere better).
To finally answer your question, yes some places forbid models to meet up with people. Others don't suggest it, but say that if you do, be very safe about it.
