Since other people are asking about related tools...

Do you know about a tool for managing personas (vulgo sockpuppets)? E.g. a little database where you store facts about fake identities: Name, age, location, hobbies, favorite topics, and so on. Maybe if you click on an identity, it will connect you with a preconfigured proxy or VPN and allow you to post as them on websites.

I don't really have a use case for myself. I'm just curious because I read a couple of years ago that the US Army was developing something like that for propaganda, and wonder if the OSINT or sousveilance people have come up with a version. A less nefarious use of such technology would be to keep your (real) online personalities separate.
