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.
Try posting in /r/conservative, I replied to a comment there once and received a bunch of bans from other subs shortly afterwards. It doesn't matter what you post, just the association with that sub is apparently enough.
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."
