Was discussing the CDC with a user (PatrickY6) on Reddit, and caught them lying.
Clicked on their history, because I wanted to see how else they lied in the past.
I read a couple of pages, and I closed it, but re-opened the user's history a minute later and it said the page does not exist.
Still get the same thing repeatedly. Can't even access the profile through private browser. I don't think it's deleted though, because his comments are still on /conspiracyundone.
I would imagine this is like the other "feature" that I mentioned, where "power users" on Reddit can hide their last comment from YOUR view, so they ALWAYS get the last word. The comments DO show up in their history, just not in the thread proper. But now it seems they can instantly hide their history from view as well.
No. You're just bumping into "eventual consistency" of a distributed database.
There is no 1 reddit server, but many. These servers do not all consult a single source of data but also many. The priority is to store comments as fast as possible and the synchronisation across multiple databases is done "eventually".
If the load balancer moves routes your requests from one server to another, you can end up on a server that hasn't received the database updates yet.
