I remember Facebook around ~2010 would often seemingly delete posts I published, or hide them from some of my friends. Or from me. I could easily confirm that by viewing my profile from another browser that wasn't logged in, or having a friend sitting next to me open my profile.

Of course, it wasn't any kind of UI bug or automated moderation. The experience gave me a visceral understanding of what eventual consistency means - a term I also first learned around that time, during internship in an Erlang company, and connected the dots.

I was one of the first people in my social circle to spot the issue, but as it became apparent over a year or two before eventually getting fixed (or at least made less obvious), I ended up giving a very high level intro to distributed databases to quite a few non-tech people, in order to alleviate their concerns about Facebook gremlins.

This and other experiences using and building software systems make me agree with you. Especially for large web platforms, that weird thing you're experiencing could be some nasty form of shadow ban, but if you just noticed it after doing something, then chances are it's just a transient issue with queues or database consistency.
