FallenKeith75 has admitted in the past that he was the banned account FallenKeith72. According to the admins even despite this, they can't do anything about it because the account "fingerprints" are different but of all the not-banned accounts that Rec called out in that post, he's the only one I'm certain is the same person.
The thing is all those accounts are banned from /r/xtrabytes now so they can't show much interest in it really outside the odd crosspost to /r/cryptocurrency. There are some indicators I don't want to reveal because they'll become useless if I do but I have reasons to strongly believe that at least 2 of the other accounts mentioned in Rec's post are the same person or other fake accounts that only exist to FUD xtrabytes.
You don't have to agree with the coin or the method that the related message was delivered in but there is clearly an organised campaign to FUD the coin. If the fact half the team has accounts impersonating them on bitcointalk wasn't enough to show that I'm not sure what will really. It irks me that I'm being impersonated here so I do understand why not everyone on the team is always rational regarding some of those fake accounts but I don't think anyone commenting or posting in good faith has been banned yet.
