I think that's a key part of the perception that comments are being "censored". I mean, as I write this comment, I am typing in a textarea (<textarea name="text" rows="6" cols="60"></textarea>), it has a few hidden fields, and that's about it. This could be a complete spam message (go visit my penis enlarger at http://someurl.com http://someurl.com), or something that adds value to the discussion. The server could pre-emptively try to work that out and automoderate, or a human could get to it later, maybe community flagging provides a signal or can be abused. Imagine state actors doing this on a ginormous scale. Troll farms with people submitting content all day every day, to try and "confuse" an AI or make it "re-learn", that would be in their bests interests if they have a particular agenda. That's what we're dealing with here.
