Wow.  I met Grant on POF in Ottawa in the summer of 2007 or 2006.  we went out once and I got a bad vibe from him.  He pursued me the rest of the summer but finally left me alone after I told him I was interested in someone else.  A year later, he contacted me again on POF and in a phone call, he insisted we meet again.  I found him annoying, not charming in the least, and a little weird.  We never met because I sensed something was wrong and called him on his behaviour and his stories. 
I'm sorry, but I can't believe that he was able to reel in so many other women.  I think more women need to listen to their spidey senses and perhaps slow down a bit when they're getting involved with a stranger.
