Even so, while I disagree with banning happening on hn, it is usually prefaced with warnings about the rules of the site by the moderators. There's decent human beings at least trying to keep the peace here and steer discussions back on-topic.

That is NOT what's happening on Twitter. Rules are not evenly applied based on politics. #acab is just fine but the gentle ribbing of "learn to code" is suspension and ban-worthy.

All depends on which group's butt is being made to hurt.
