Only post prior to coming back from 5 years of inactivity was vouching for a transaction with Dealerboy, a large one, so i'm guessing it's a self vouch. Additionally Dealerboy is TWC'd so there's a strong possibility he was caught for fake/self vouches anyways. Also wouldn't be surprised if it's a hacked profile given the low post count/inactivity/low likelihood that someone would recover such a profile.

As for the others i'm not sure which are fake and which aren't but just assumed Oblivious should take priority as the only active one.

 

They're not the same person, but they do appear to be fake vouches. I've permanently banned them for fake vouching in order to scam.
