Showerthoughts was one I tried. I don't remember specifics but I tried a couple times to post actual thoughts I had in the shower and they got insta-banned by a bot so I just gave up.

Lemmy is just small enough at this point where mods don't have to rely on automated tools and things like required flairs to effectively manage their community. As it develops, things like required flairs, verified submissions, etc will become more normal.

For example, I'm watching Wheel of Time, and /r/WoT requires you to flair every submission with a spoiler level (books only, show and book, show only, etc). Lemmy can't really sustain good discussion on that yet, but when it does mods will need to start aggressively removing submissions if they're not properly categorized.

Oh I did and even contacted moderators a few times to try to have posts reinstated after they were insta-banned by a bot. I just got tired of fighting with it every time I wanted to participate.
