Look at any authoritarian regime. Once they decide that a particular person has to be destroyed, they dig through their entire history to compile a dossier of Evil Things that person has said and done. You need searchable history for that, though. Or a lot of manpower. But databases are better for that purpose.
Similarly, if you can show that (unwanted person) said the N-word in 2004, you can probably get them destroyed today i the U.S. The hit piece just writes itself.
