Huh. After further digging, I found four accounts that were started within two days of each other back in 2000 that have all used the same IP address that is NOT an AOL address. One was MrBlond. Two haven't been used since 2001. But one was used on December 6th, 2010.
That same account matches around 10 different IP's that MrBlond used. It could be complete coincidence. But it might not be.
If any of you guys feel like you knew his personality really well, shoot me a PM, and I'll tell you who the other one is. Perhaps you will be able to get a feel for whether or not it's a possibility that he's been around more than we thought...
