I never heard of anybody having their iCloud account blocked after using hackintosh and I have qhuite a few friends using it. I think as long as you have actual apple products connected to that account, they won’t block it as to not deter their customers.
The only case I read was on reddit, but they created a new account from scratch and the ban might not even have been related to the hackintosh but just because it was deemed suspicious.
That would be a very spezial drink
