You assume people stealing your private details for using it against you, are going to use it unaltered and in context. With enough bad faith and some manipulation, or just a bit of a twist, anything can be weaponized against you.

If private data is stored, there's already a chance of it getting out. You may get lucky, you may not, but for someone that hates you enough, any random detail can be a weapon. Even stuff that doesn't depend on your actions, like religion, country of origin or even medical details. People you associate with, even at a superficial level, can make you guilty by association. And let's not get into stuff like porn habits...

Political manipulation can be made real easy if they got dirt on you, too.
