There are some big wins that they've never taken care of, despite spez talking big about fixing them, e.g.: stop allowing mods to pre-emptively ban you. I don't know anyone who uses Reddit that isn't banned from r/pics simply because they posted somewhere else on Reddit. The list of subs they ban for is huge.
That's pretty crazy. I've been on reddit since its inception and have never been banned from pics despite having posted on all kinds of unsavory subreddits over the decades.
If I cared about it. I might want to find a set of subs which when you simultaneously post in will result in largest number of bans. Would be interesting experiment. Exactly how many posts you need to get banned from largest number of sub-reddits...
If you're at the point where you have been vetted and allowed to post on r/Conservative, you've gone way past mere "association." This isn't like some board game forum where you can just create an account and start posting. r/Conservative (probably with good reason) has a long and very active vetting process before you're allowed to post there, and only posts that conform to their ideology stay up. So getting banned for participating is a little more than just "guilt by association."
You need to send a photo of your FSB / KGB id to be able to get recognized as a true conservative from USA + you need to post the propaganda of the day
