Not trying to help or defend OP, but you guys need to read the post again. He never accused the mentioned accounts of cheating; So no need to ask for evidence that you're looking for. I think he only noticed that Woodie and BitcoinHunter have the same username on different platforms. I understand that you guys assume if someone posts here in reputation board you think there's something wrong or someone is cheating but its not. , I do agree to lock this thread since Woodie already mentioned that they're different user.
I agree with you.
OP did not accuse them of being alt. Since both of them have same username on different platforms, he finds it interesting but did not dig out. So he posted it here in case anyone want to dig out further. Because we have seen a lot of cases where people posted some clues and then several forum members came with more information about these accounts. Since OP is not accusing of anything like, cheating on any campaigns, it is okay in my opinion.
