I use Bellingcat's Toolkit, it's constantly updated by people who do this for a living: https://bellingcat.gitbook.io/toolkit/
Totally fair question. That particular tool is more situational, it can surface quotes tied to a username, which can help spot ideological lean, professional background, or even cross-platform clues if phrasing is reused elsewhere. It’s less about hard identifiers, more about building contextual profiles when attribution is subtle.
That said, I’m always reviewing which tools actually add value. If something feels out of place, I’m open to removing or recategorizing it.
