Many users face issues during signups. If users have ability to delete the account (of course ONLY after authenticating using 2-Factor Authentication) many new user sign ups would be smooth.
Users could be associated with a automatic account number rather than email as unique identifier. That unique identifier could be abstracted/hidden from the user (internal to Visible).
Also this would satisfy many privacy concerned users who would be relieved knowing that their data is purged after X number of days. (Visible could update the privacy policy accordingly)
Visible can implement this approach if not already present.
