I had already thought that from the beginning, the whole thing about him being around kids..I think the different points of view I'm getting here is what made me think of dropping it. However, I contacted another teacher friend of mine who contacted her state rep. There really is nothing I can do without the evidence, basically if he manages to contact me again I will tell him that I will report any further conversations. I looked on the website and there is a way to unblock a person, he is not on the block list so I think he blocked me in return. Or he deleted his profile.
I think he is not as smart as he thought he was, even by using aliases, he had let me see his face, he mentioned his occupation and I knew he lived nearby, and when he called his location came up on my phone. It didn't take a lot of investigation to find his profile on the school website along with his picture.
So I think if he tries to continue to act like this, he will get caught. the fact that he might have blocked me or deleted his profile tells me he is concerned.
