What problem would you like to solve? Please describe:
Contact methods can be created, without verification, that sit forever. This can be an issue if a user mistypes a contact method value (like phone number) and then never deletes it because other users cannot add the same value.

Describe the solution you'd like:
Cleanup contact methods when their verification code expires if they've been created recently.

Describe alternatives you've considered:
N/A this would need to be handled manually by an admin or individual users.

Additional context:
Should we also clean up contact methods that have been disabled for long periods?
