Given the recent... drama about a certain player's doxing I think the actual legal repercussions of doxing should be accounted for in the length of a dox ban.
Being a victim of doxing on this server myself - a player on CM attempted to impersonate my real identity on Discord using my real name and LinkedIn profile picture - and an avid watcher of a streamer who has been thoroughly doxed and is constantly screwed with every day, I think it would be safe to say that any attempts at leaking any player's personal information without their consent should be met with a very strict and clear ban.
it is simply just to teach how devastating dox could actually be, especially in this digital age where you can easily search up for phone numbers in another state or region and call in a bomb/SWAT team threat or order unpaid pizza for people. Private personal information, in the wrong hands, can ruin people's lives and I honestly hope everyone can agree that doxing should not be tolerated here in the slightest.
My suggestion is to make it a 1-month IP ban. This allows the victim of the doxxing to remain safe from harassment by the doxer, since they won't be able to join on any alts, and gives the doxer themselves a month-long reason to think about why they screwed up. Or leave forever, which works too.
Of course, there's the exception of casually using someone's first name in a conversation. For example some people call me Jared and I'm fine with that. This exception probably should be treated differently, in that if person A uses person B's personal name, and person B objects to it or contacts staff, then person A should be warned for the offense and banned normally if they continue for any malicious reason.
Otherwise it's pretty clear when someone steps out of that casual "first name" zone of personal information and goes into dropping addresses, last names, phone numbers and all that.
