You are not shadow-banned from what I can tell. Your lists of submissions and comments seem fine. There is a particular submission that is [dead] which makes it look like it was automatically tagged by the system.
It would be useful if there was some kind of central place to learn about various "unexpected" behavior of HN, maybe something crowdsourced. I am just writing it down here since you have probably more experience !
It's actually ironic in that case since I specifically chose what I thought was a reputable source as I didn't want the conversation to be derailed by stupid arguments veering into conspiracy territory; silly me :) .
I should update my prior on the reputation of that source.
(Edit: the original comment I replied to was a bit different, the structure changed while I was writing my reply)
Which shouldn't be a problem.
