Oh it's more advanced now. I'm banned from a whole slew of subreddits for daring to even exist in another subreddit. Preemptive silencing is widespread.

Often times your comment won’t even appear if you’re a new user, haven’t posted in that subreddit before, or your kharma is too low.

I posted a polite refutation of a very smarmy, incorrect post (as most of them are) on /r/neoliberal and it appeared to submit, but after an hour and no downvotes or upvotes I opened the thread in a Private window and my comment was never actually made public.

The irony is I'm amazed at the subreddits that exist and its a YC Top Company @ #10!
