I blocked a harasser and now they've found a way to send iMessages despite that
On August 23, 2025, I blocked an ex-friend who reached out to me out of the blue. He was a toxic presence in my life and it had been years since we'd talked or communicated in any way. Despite blocking him on all platforms, including my iPhone 15 Pro Max, he was able to send me messages on iMessage on September 1, 2025 and on September 2, 2025.
I've seen some articles online that suggest a person can change their AppleID in order to bypass blocking of their phone number. Might this be what he did? Is there any way to block him more thoroughly with Apple technology or do I need to figure out what additional steps to take?
Thank you.
