The /r/conservative subreddit is unpopular among actual conservatives because it’s basically a propaganda outlet for the mods.
You can get banned for posting traditional conservative opinions there if they go against the message the mods want to allow, even if it’s conservative.
Don’t be tricked into thinking it’s some conservative safe space. It’s a propaganda outlet for the mods who ban even conservatives if they don’t toe the line and agree with the mods.
Do you have examples? I wouldn't say it never happened, but a repeatable pattern should be easy to see.
