I got the same pms from the same guy too, 3 separate messages. I have e-mailed the webmaster with a copy of two of the messages. I sent a message to webmaster@disneyinfo.com but there is also another e-mail address you could try admin@wdwinfo.com. These are the two I found unless someone with more knowledge finds your thread and tells us differently.
I wonder if anybody else on the Expo thread has gotten something from him too. Since it we are both frequently over there, maybe that is where he is lurking?! I think I will head over and ask there.
