I have actually seen lots of people fail the trivia. Not necessarily get kicked, but usually asked by a wingman or someone who's hosting a floor that isn't a keyer, etc. Many people end up reading the guidelines, at least they say, over and over (omfg 6 taims@@ except not), and cannot find it. This is probably because a lot of people don't think that trivia is that important, they'll open up the tab, without really reading it, and just think it's for a bit of fun. I think an acceptable way to manage things is to tell them to read the guidelines, ask them afterwards, and if they can't figure it out, then just emphasize that they have to read the ENTIRE first post of guidelines. At that point tbh, I'd personally make sure to read every tab, specifically the one that I may have skimmed over previously. Anyways, just emphasizing that they have to read the entire post, rather than just saying, "Re-read or you'll get kicked." Or whatever. Just a thought.
