Tom was one of Frank's favorite posters. Partly, I think for his posting on a newsgroup that he was stealing from the till on a regular basis. The Dump seemed to admire him for his felonies.
IIRC he got in trouble for encouraging the Palestinians to continue the job Hitler started.
He showed up under another name and so far as I know, his new identity is still posting.
I don't believe he ever actually lived there though. His real residence is probably the Rio Linda area of Sacramento.
