Not necessarily. Maybe someone wants to end their life, but they’re too optimistic? Wade through one of the scrapes you get, and you’ll be suicidal in an hour!
Point it at an archive of /pol/, work some deep learning magic to link posts from the same person together, then point it at the wider Web and start deanonymizing. You couldn't catch everyone, but you might do some good.
So doxing kids is your idea of doing "some good"...seems a bit weird to me tbh.
