How Does Shadowbanning Work?

Hi. I’m newbie789 and I just noticed that all of my posts for over a week have been hidden from public view. I haven’t received any warnings from the mods, the only time any post of mine have been flagged they’ve been rightfully vouched for, and I’ve accumulated over 1100 karma points.

Is this at the request of a particular poster or group of posters? I have a habit of calling out silly low-effort self-indulgent blog posts (which I find to be a common waste of first page real estate.) Did I offend the Blog Gods? Somehow my posting is so offensive as to deserve being hidden from the average users but not so offensive that it gets downvoted?
