Do not post pictures of humans online who cannot consent to you doing so.
I'm so happy my parents never got into social media before my adulthood. There was some overlap there where they could have plastered images of me all over their facebook feeds without my understanding what that meant.
It's fucking revolting to me to see how normal some people seem to think it is for a parent to do that. IMO it should be straight up illegal and a violation of a child's right to privacy.
