First time I ever got a random AirDrop was a dick pic while I riding the subway in NYC. Somebody just sending dick pics to strangers on the subway.
I hadn't realized Apple had created a whole new avenue for sexual harassment. Great. Apparently at some point in the past I'd changed from the default "contacts only" to "everyone" without realizing what it would open me up to.
Obviously it seems like technologically there ought to be a way to identify the sending phone and pass it to the police to find the perp and charge them with a hefty fine at a minimum... but I'd already deleted it (of course) and didn't have the time.
Still, seems like Apple ought to provide a kind of "report abuse" mechanism that would disable it from your Apple ID, or something.
Also, maybe when an image is from someone not in your contacts... don't show a preview??? Or make it super-super blurry, so you can reject it without being subjected to it?
