Unless you are actually the author of the page (and that person has another account here on HN, so if so why use a new account and not that one?), it's strange to copy/paste the contents of a page and use the material as if you wrote it yourself.
I am the author :) I got shadowbanned, I don't know why.
You used the other account almost entirely for self-promotion. That goes against the guidelines and often ends up in things like bans.
I’ve been a passive reader for years, but you’re absolutely right, the posts I was sharing were indeed self-promotion. Thanks for pointing that out. I will be more active in the community this time.
