Wait, Threads is supposed to be a Fediverse thing? I'll admit, I kinda noped on it as soon as I heard Meta was behind it, but how does the Fediverse fit into all this?
Honestly, one of my favourite subs despite the very strict moderation (every post had to be manually approved) was r/tombstoning. Literally just images of newspaper articles where the headline and any related images/articles were very unfortunately placed. The mods basically ensured no reposts or posts that weren't quite correct got in - so the sub basically got a reputation of only having a post every other week or so, but when you saw a tombstoning post you'd know it was quality.
