There are a few things you can do to stop maybe contacts from happening on your iPhone.

  1. Disable the “maybe contacts” feature on your iPhone. This will prevent any future contact requests from being sent to your phone.
  2. Delete any potentially relevant contact information from your phone, including addresses, phone numbers, and email addresses. This will help to reduce the chances of accidentally sending out a contact request in the future.
  3. Use a different email address for all of your contact requests - this will help to avoid any potential confusion or issues down the line should someone try to send you a contact request through an old email address.
