So besides the amusing part is that conclusive evidence of a clone? Good but not a smoking gun type? Just a quirky coincidence?
It's either the same person, or two people posting from the same internet connection. Who apparently don't know each other. And who apparently live in Fort Wayne, Indiana.
Back in the days when I used to admin on another political type board, (my god, has it been 9 or 10 years already), the same IP generally meant (where dialup was still the norm, or it was just a one computer cable connection, no wireless routers), the same computer...some people explained it as siblings on the same computer, but you knew it was the same computer.
Is that still the case? Or could it be multiple computers from one wireless router? Or has IP masking/proxy become so good that one can imitate someone else's IP?
