I figured out where a model was from based on info I knew about her and furthering my search. She said she lived around 100KM outside of the city she lives now. So I was digging info about her and a guy from her country mentioned the name of the city she lived in on mycamgirl site. I put it into google maps to see distance between that city and her current city and it was about 100KM. I then looked more into her profile pics and saw the name of a photographer listed there, as a watermark. I searched him on FB and then found his profile and that he was based in that city. She did modeling work for him when she was younger before moving to her current city. I tried looking at all his 3,000 friends to see if she was on it, but either overlooked her by accident or she isn't a friend of him on FB.
1 bit of information can lead to more and more if you have the time to do it yourself or the money to hire professionals. And if you are not going to hurt anyone, just figure out which club you need to go to a lot or place to act fly, then its perfectly ok to find out more about models. There's a probability she will date you and overlook the fact you did that, as well as the probability of her hating you and not dating you. But if you do not try there is no probability of the first one and the second one is just the same for the end result.
If a guy really misses a model and likes her a lot, why not try to find her and see if she will date you. Its better then staying home crying and being depressed. Online stuff is imho just an extension of the "offline world".
