Well if you started doing your research then your a smart one. Here I will list a few e-mail addresses to watch out for that try to convience you other wise that they are a modelling agency. If it was a real agency they would have contacted you to meet in person. No modelling agency would have you or make you strip on webcam.
Thought to make aware to everyone to make sure that their dreams aren't shattered from these people. Don't them fool you!
