Let's start by saying: cool, it's satire, and learning technologies through novel applications is the heart of hacking. I ain't even mad.
But no, shadowbanning is not cool. It was originally for spammers, not for real people you don't like. It's inconsiderate, because if effective, it wastes peoples' time writing comments they think people can read. Comments they believe contribute to the conversation. And it's not cool.
And to be clear to jMyles: This is trickery.
Disclaimer: I was shadowbanned many moons ago (hence the name now) for one comment out of hundreds I'd made on this site. That one comment was rude and terse, but not something unequivocally hateful or harmful. For that, I posted for weeks without knowing my comments re: the technologies and news I care about were being blocked. It's not cool.
