Sorry, I never got notifications for these.
Unfortunately, Apple calls everything "fraud" so they can justify themselves. It could be just a similar icon, an app name, bought reviews, bait-and-switch, deceiving users... everything is fraud in Apple's eyes.
Many accounts got banned and unfortunately nobody got their account back. Especially the ones with name "veo", "nano banana", "sora"
Apple don't want to get receive complaints from other big brothers, so they just terminate your account as a shorthand.
Did your friend get their account back? Hope they did.
Edit: just read the post above. So he's still waiting. Good luck!
