Note that word 'repeatedly'. When people post like https://news.ycombinator.com/item?id=20958824 and https://news.ycombinator.com/item?id=20902321 and ignore our requests to stop breaking the guidelines, we ban them. If we didn't, the guidelines wouldn't mean much.

Sadly, it's my business to deal with flamewars, personal attacks, trolling, and other abuses of HN. If flames are allowed to burn this place to a crisp, HN won't be HN anymore. And eventually there wouldn't be anything worth running or anyone to run it for.
