Why you should never give out your picture to strangers?
Why you should never give out your picture to strangers? In fact, you should never send your photos to anyone in any form! You never know how they'll be used. Not only is it unsafe (be aware of human trafficking), when someone, especially someone you don't know, is asking for a picture of you I'd be willing to bet there are no good intentions behind it.
Is it rude to photograph strangers?
“Generally, you can take any photos you want of people when they are in a public location, like a park, a beach or a city square. It's perfectly legal since they have elected to place themselves in a public location and have no reasonable expectation of privacy.
