I find it unlikely that people a government would want to kill by drone strike would be posting about their wherabouts on social media and at the same time obfuscating their location by having their phone move without them (by someone ok with being hit by a drone strike?).

Or we're speaking about striking civilians posting on social media - where I'm not sure drone strikes are very cost effective or pertinent.

My understanding is that drone strikes aren't a thing done because you just got a hit on social media of a precise location, but more of a somewhat long investigation into the activity and identity of the target, their habits and movements (both to confirm their value and maximise sucess) - and then a calculated drone strike that both maximizes sucess and minimizes collateral.

Of course Israel does not do this and is more into the "paint a bullseye around the victim" kind of doctrine, but that's outside the scope of this discussion.
