That's your opinion, but that's not how it works. If you could get a frequent location update from the same iPhone about your AirTag accompanying that iPhone, you would be able to stalk anyone by planting an AirTag on them or their possessions and then placing your AirTag in Lost Mode. This is obviously not the case. Apple intentionally enabled anti-stalking measures in the AirTag, so if the iPhone detects that someone's AirTag in its proximity moves int he same pattern as the iPhone itself, the iPhone will stop updating its location for the AirTag's owner to see the location of the AirTag to prevent being stalked by the AirTag.
Putting the AirTag in Lost Mode does two things:
- Your iPhone is supposed to notify you when the AirTag is detected by someone else's iPhone when you place your AirTag in Lost Mode.
- The person who finds your AirTag could read a message you leave by scanning the AirTag with their phone's NFC - be it iPhone or Android. Then, they would be able to reach out to you to return your item.
I wish placing the AirTag in Lost Mode would make it sound an alarm when it encounters someone else's iPhone, but, unfortunately, Apple didn't implement this feature. Therefore, the AirTag can only sound an alarm when the iPhone it's registered to is in the Bluetooth proximity of the AirTag.
