Who Is This Person?
A fast read on a public account, plus the history the SuperX account already has with them.
superx x:user <handle>
superx x:user-posts <handle> --no-reposts --limit 20
superx contacts:get <x-user-id>
superx contacts:replies <x-user-id> --sort recent --limit 5contacts:get covers known contacts only: engagers, contact-list members and scored leads. A 404 there means the person is not one of them yet, not that the lookup failed.
