I'm guessing that there's an unexciting explanation for this, but I noticed an old post [1] that was authored by "Anonymous", but edited by Satoshi:
Satoshi edited the post, but he did not author the post.
I think it was something pretty mundane. Possibly an external link, removing a name, some small line that was near the end.
Does anyone know what's up with that post?
The user deleted his account, but after Satoshi had edited the post.
Maybe it's one of Satoshi's (although it's in a distinctly different style), but he didn't want his name attached to it?
It's not Satoshi.
Maybe it's not his (more likely), but he edited it as a moderator? But then, why the edit? I'm not sure how moderation worked back then, but this post seems unlikely to have contained a spam link or anything objectionable.
It wasn't that it included spam. There was something in it, it was a funny phrase, link, or something identifying, just a line or two, and Satoshi removed it. Satoshi was light on moderation, but there was also less of a need.
