Did the family get a spam invitation and the information leaked?

This is because: the generation of spam advertisements for family invitations is actually an invitation mechanism for family apps on your iPhone. Open the Family App- click Family Settings in the upper left corner-select your family-click Invite others, and you can invite others and send messages. Some lawless elements use this script to send spam advertisements in batches.

Solution: Click the AppleID option in the Apple phone settings. Click the iCloud option below to enter. Turn off the switch of the home option to solve the spam invitation received by phone home app.
