What are the worst things Reddit admins/mods did? Especially that can't be talked about on Reddit.
Employing Ghislaine Maxwell has to top the list. Changing their community rules definition of hate speech to only be against chosen groups has to count too. But there's a lot of bad stuff that redditors quietly accepted, forgot, or newer members never heard of.
I also seem to recall one of the gun subreddits, I don't remember if it was guns or firearms or weekendgunnit, asking express permission to etch the reddit logo and subreddit name into a gun. They received permission, posted pictures, and later received a cease and desist.
