But until jimbo gets I.P. banned (or at least an I.P. address check on both gets done) we'll never really know for sure, because both of them are going to deny being the same person, whether or not they really are. If they aren't, that's what they'll say. If they are the same person, "they" will say "they" aren't anyway to cover it up. Also, joe_H's proper grammar and spelling and educated opinions make it seem like he's not jimbo, but that might just be jimbo doing that anyway to avoid being suspected...
Well, whatever. It's an interesting theory and there are definitely similarities between the two of them, but I think I'll wait this one out and see what happens. They might be the same person, they might be two different people and it could all be a coincidence.
