Are you saying he just cloned the wallet? How is that a problem? GUE had a clean wallet and a lot of people have emulated it. If he had created the wallet himself, all of his other wallets would pretty much have the same signature so this is a moot point.

If this guy really is the same Mac McLaughlin that works for Fibonacci (and all signs point to yes) then it's more likely that he isn't making mistakes at all. He probably had his website shut off to prevent people from knowing who he was before the big reveal. He seems very well spoken from his previous posts and does not strike me as your typical dev who doesn't know where to place a comma or form a sentence. I imagine he's accumulating coins.
