I have never seen any warnings from Google or Facebook if I automate against my own accounts, and dumping the data. Only on sign-in attempts. That kind of warning is very limited, and Apple also have them.

It seems like Apple now have introduced ‘honey pots’ and other techniques to discover if there already is someone with access to your account/device, and that is a big deal and good news. And something I have never seen from any of the other big companies.
