The guy sounds like a classic predator--and a very good one. I especially liked the part where the contact email and LJ account for one of the groups people were trying to warn went through him... so obviously, no warning got through. Nice.

This is charivari at its finest. I hope it works.

It looks like the mods are willing to allow the post once they have proof that the allegations are real, since it sounds like they got burnt by false allegations a while back. OTOH, they don't seem to be moving their asses to find any proof.
