Although I've not seen the two in the same room at the same time, I'm downright positive that Fancy and Traveling Gentleman are not the same person. I'm pretty darn sure that Clark Kent ain't Batman too.
I don't know what the gent got banned for, but I don't think it was for having two accounts.
I've had multiple correspondence with both, when TG first appeared and was looking for a newbie friendly provider, I pointed him in Fancy's direction stating that she would be able to give him a solid reference and a wealth of hobby knowledge.
Yes, I agree. Most likely that's what the BAN was issued for. I've never met either in person, so can't vouch for one or the other. But from my correspondence with both, it doesn't appear possible they can be the same person. Whatever evidence the mods have most be solid to hold up to scrutiny. Everyone knows how well liked Fancy was, this doesn't fit with her online persona. Ya never know though.
