If they're here I doubt they'll last very long. The kind of shitbags that do cowardly stuff like that don't last very long in spaces where we don't play the 'everyone get along!' game.
I used to listen to the He-Man.org podcast and it was almost entirely because of Eamon. Even when I don't agree with him, I loved his enthusiasm and he just seemed so kind and lovable.
Well then, I have my suspicions (not confirmed, just who I know have a vendetta against Randy and seem the type to do it)--
CobraShadowJoes. Steve Wagner and whatever his little yippy tagalong's name is.
They were former friends of Randy's, actually would hang out with him outside of Cons and such. They had a massive falling out, and would trash him any opportunity they got. And I'm talking are banned from NECA's booth at any and every show--THAT bad.
They seem like the type to leak his personal number out of spite. They are legit two of the most imbalanced, immature, borderline psychotic people I have ever known. Particularly Steve.
Again, could not possibly confirm, not an accusation, just who I suspect. I could be massively incorrect.
And yes, at the opposite end of the spectrum, everything you mentioned about Eamon, he is that and more. SUCH a nice guy, and his beautiful girlfriend was such a sweetheart.
