Went to a day rave which prohibits phone cameras yesterday. As a pedantic engineer I love pointing out how easily defeated such measures are, but it does make a difference. Far fewer people pointing a camera at me which makes me a lot more confident.
@jmacarthur that sort of thing feels less like a technical measure and more a clear bit of setting the cultural norms by asking anyone who wants to violate them to make a clear choice in removing the sticker.
@jmacarthur there’s a big difference in the choice to “take a quick photo, I’ll try to make sure nobody’s face is in it” and “I’m going to remove this thing put in place to block my camera from working”.
