The human mind is wonderful at detecting patterns... even if there's nothing there but random noise.

That seems like a big stretch to me to discern purpose from a password file. How would he even know that the 666th person had just registered, unless
Bruce Wagner and MagicalTux are the same person?
I could just as easily conclude that Bruce
deliberately tried to be user 666, but was a second too late.
(note password--not starting with $1$)
I'm no expert on the MtGox password file leak, but if I recall correctly what I had read back then, a password not starting with $1$ indicates that it wasn't changed by the user at some point after MtGox changed their hashing algorithm. Or more accurately, the $1$ passwords in that region of the file belong to people who did change their password at some point after the hashing algorithm changed. If I was going to draw any conclusions from that at all, I'd say that two actively-used accounts in which one has a $1$ password and the other doesn't, are less likely to belong to the same person, since a given person would probably revise the passwords of all of their actively-used accounts on a site if they were going to revise any of them.
