Don't get invested in subreddits. Most of the original mods that cared about their subreddit are gone or have put modlords in their place. A modlord being one that lord's over many subreddits, typically for a financial or social gain, of which you will be banned at the sign of any criticism. Reddit corporate does not enforce their rules on subreddit mods. It's a show. You can have mods harass you and they'll do nothi…
This may be true for top subreddits but definitely not all. Especially the ones mentioned in the website. Like I doubt there are any powermods on r/ProgrammingLanguages. Also it's not like you're saying anything remotely politically incorrect on those subs either.
What is considered "politically incorrect" is not universal. Software has plenty of its strong opinions and people whom want to squash opinions. Over time some subreddits get taken over and used for personal benefit. Lots of crypto schemes and people looking to sell things. The bans generally don't happen over technical disagreements, they happen when a mod themselves gets inflammatory with users and users push back.
Simply what I'm saying is reddit is designed against communities, don't get invested. There's useful stuff but underneath it's not any different from boards of old.
