You're welcome. :)
A more useful description might be:
"ZOT" is the action of the Admin Moderator, or in some instances site owner Jim Robinson himself, nuking the posting account of a FReeper who has been making trouble (hurling insults, posting obscenity, trolling, post-and-run, boosting socialism, backing Romney or other frowned-upon folks, etc.), or pulling a thread with any of the above. The account may be "suspended" (posting privs gone but the account remains) or "banned" (account is disabled). The thread may be pulled entirely, or just set aside with a History link, to allow examination and critique.
The term "ZOT" derives from the legendary Johnny Hart comic strip "B.C.", where (in some cases) the anteater would shoot out his tongue and eat an ant, or (in other cases) it was lightning or similar. Other comics would use "POW!" or "BAM!".... B.C. used "ZOT!".
Johnny Hart is a much-honored artist around FR, not only for his wonderful funny strips, and the ZOT, but also his overt and unapologetic conservative and Christian themes in his later work. He took a lot of flak from the MSM for that. I'm proud to say that Johnny Hart lived and worked in the Broome County, NY area, which is very near my own home.
There exist threads devoted to the History of the ZOT on FR, including the "Undead Threads". They are hilarious. At the moment I don't have a link for you but if I can find one I'll post it. Maybe someone else will....
There is also the FR Lexicon Thread. That one is similarly useful to a new FReeper
The 2009 FreeRepublic Lexicon (Lingo, Dictionary, Lore Handbook)
There is a section about 40% of the way down that thread, on the history of the ZOT.
It's all in the light spirit of good fun, of course.
I have pinged Laz for any comment. (Also, it's considered proper/polite FR etiquette to ping any FReeper you mention in a post.)
Most of the time, when I post "I'd hit it" I already have.
And let me tell you, that old tree stump was SWEEEEEEEEEEETtttt....
