I don't see how this is any different from discovering years later that he had 10 pounds of gold buried in the backyard, a situation I'm sure you have some legal recourse in.
It appears flagged to me but I was able to see it before. Maybe it took a while to show up, so the user edited the comment to complain about Marxist moderation, unaware that it had not been removed by mods, causing the mods to remove it..?
Why are you still here? Your profile says you left, and your comment history indicates that you're convinced everyone here is wrong (but you, of course), and/or actively silencing you. I really don't understand that kind of behavior!
I don't really, but lots of comments in same thread. Its probably really hard to moderate at hn scale, they brought on a new guy not too long ago who afaik still mods under dangs alias. Have you sent them an email to ask for an unban?
