We could not yet verify a single trust point for you against a public source, so there is no badge to issue — it carries a check date, and we will not print one we did not earn. Point us at a public page (a DPA, a trust centre, a certificate, an imprint) and we will re-check; the badge follows automatically.

Claiming the profile with a work email gets you a form for correcting anything we got wrong, and a note whenever we re-check you.
