A zot is a thread that gets pulled, or nuked, usually something deranged posted by a troll like this one. IBTZ is just a little game people play trying to post on a zot-able thread before it's yanked. It's amazing this one has lasted so long. I guess they're giving us our Friday afternoon fun.

Now I am assuming the keywords are listed so maybe their (the zotted person's) stuff can come up again if they put in a keyword. But that doesn't make sense as their threads/posts are deleted. Oh well, I don't want to give an education to any trolls who aren't in the know, but if anyone can give me a nudge on the importance of posting keywords, I'll do the research, if there is anything of importance about their use. If not, thanks for the heads up on the other issue. How very fun. Can't wait until the next one.
