There is no such thing as a shadow ban. I have access to a ton of IP space so you won't be able to prevent me from checking the public-facing site to see if my posts are shadow-banned, at which point I will just make a new account.
Trust me, having to read my comments is not the worst thing that could be happening to this site. If I wanted to be mean, I would set up a botnet to flood the front page for like 5$ of sats a day.
I think it is pretty interesting that no one here understands the nature of sybil attacks, seeing as that's the one thing this site was designed to prevent.
