Sounds awesome & makes airtags more appealing, but if apple is just going to shut it down next week then less so
Over the past year only of my accounts has been banned by Apple, and I was using that one to request locations every 5-10 minutes 24/7 in Home Assistant, with no other usage of the account other than one registered hackintosh. I'm currently using another account that is querying data every 15-30 minutes, which has been working fine so far. You just need an account to anonymously download location reports, so if your throwaway gets banned just create a new one and things should work again. Just make sure to attach it to a real device or hackintosh at least once to "activate" the account's iCloud API.
I do just want to make it clear that I have no intentions on keeping this working "at all costs" - at least not without other people willing to help me out. The library is currently not even trying to be stealthy, and it can be easily detected using heuristics if they really wanted to.
