To add onto this - I have had my entire account shadow-banned when I wrote a popular technical article about blockchain technology (also about my startup). It looked fine to me when I was logged in, but it showed up as a 404 to people who clicked on it. No notice. No explanation. I wrote about this Kafkaesque expereince here. Make sure to post in multiple places.
