It’s worse than that. On r/news they shadow ban anybody who doesn’t have verified email. No message or anything. Just nobody sees your comments. I probably made 20 or more comments there over a few months before I figured it out. It felt humiliating.
It's even worse than that. They preemptively ban you outright on lots of major subs for posting on other subs. For instance, I can't interact with r/pics because I once commented on r/redditachievements. And a housemate once upvoted a pic on there which got us both banned for a week because Reddit thought I was trying to do a run-around on the ban.
I still love Reddit for all its flaws though.
