There’s a couple of people on SM I follow who use them.

There’s a street photographer called Bleg who always explains to people that he is using them to record the interaction.

Another is a guy that feeds several cat colonies on his mail route (first class whiskers) so he can use both hands to stroke and feed the cats.

Another is a guy called AsamaPOV that visits small family run restaurants in Japan and like the first guy, always explains and asks permission.

They’re examples of nice people but the scope for abuse is so wide
