So this guy shows up claiming to be A Fat Ghost, returning under a different username because he "lost access" to his original account. When asked about that, he was evasive and has, in my opinion, been kind of over-the-top about his fat-ghost-ness. I'm not saying that he's someone spoofing Ghost, but I'm not ready to take him at his word yet either. Let's keep an eye on this'un until we can get more concrete confirmation that he is who he says he is.
Edit: In fact, almost everything this guy is saying/doing can be traced right back to the old blurb that Ghost had on the Staff List when he was active:
Our laid back friend from the wilds of Canadia. Tends to use the term 'son' a lot, so don't get offended. Our resident Metric God. Use Metric, or he shall smite thee mightily with the Hiker. Very mellow, eh? Also one of our chat admins. He's one of the guys to go to if you want help with an SCP idea; he's both very friendly, and knows what the hell he's talking about.
Again, this could be because he actually is Ghost, but I'm suspicious.
Giving bearhugs to the unsuspecting since 1872.
