Thoughts
Nevermind
Original content was "I think I got banned from HN for posting meta-commentary lol we're rolling boys."
I'm paranoid about being shadow-banned from websites in general, after my experiences on Khan Academy. And I have show-dead on HN on, and there are a lot of people there shadow banned. (If you only post links to your own blog, and never do anything else, you get auto-banned pretty quickly. And those people keep posting links to their own blog, ignorant.)
Anyways, what happened above was that I checked in a private tab if my most recent comment existed pretty quickly after I posted it, and it didn't and I freaked out. It can't have been flagged or downvoted, since I checked quickly. But if you access HN and you're not logged in, you hit a CDN with a cached version of the page. (If you're logged in, it can't cache since it has to put in your username in the top right.) So when I checked again just now my comments showed up, so I think I just needed to give the CDN a minute.
