Hi,

This is the weirdest usage of crowd sourcing that I have
yet seen. Tracking aircraft using crowd sourcing is not
what I would expect someone to do.

How is it legal to track private planes like Elon Musk's?
Twitter’s decision to ban accounts that tracked private
planes, including one tracking its new CEO, has prompted
questions about what flight information is publicly available.
