Apple blocked imessage, accused of spam! Said can only unblock 1x

My daughter's imessage stopped working. After days of frustration, and hours on phone with various support agents, and rebooting phone to factory settings, we finally got to the bottom of it- She was blocked - accused of spam.

She is not spamming. I am trying to find out if anyone else is having this happen. An old discussion touched on topic, and stated that the apple support representative said even 1 person reporting someone as spam, could result in this happening.

Our support person stated that they can unblock 1x as a courtesy, BUT if it happens again, it could result in fines, even being completely blocked out of her apple id. Which of course stores decade's worth of pics, memories and contacts. Our support person said too it could be 1, 3, 5 pp reporting, they don't have a formula shared with them. She just had to read us the disclaimer.

I'm trying to look for a link that states HOW THIS WORKS. Where did we agree to this ...the terms of how someone is reported, and ramifications, etc. I'd like to read on apples legals...can 1 person really report you as spam & it just is?

If this happened to you, please share your experience. I already gave feedback. I plan to recall apple support to see if they can provide me a link to the legals as well.
