Why Facebook rejects most disposable email services
Meta maintains massive blocklists of burner domains. When you sign up for Facebook with an address like user@random-mail.xyz, the platform frequently refuses it outright or shadows your account. A real temp Gmail sidesteps the blocklist entirely because the domain — gmail.com — is the most trusted mailbox provider on the planet.
This matters twice as much when you are recovering a locked account. Facebook’s automated review systems look for signals that an address is legitimate. Genuine Google inboxes pass that sniff test; burner domains fail it and often trigger an even longer review window.
