 They didn't ask to go viral. Posting on social media without consent is immoral. If you're just out in public that you don't really have a reasonable expectation of privacy because you're walking down the street. I may have the right to take a video of a stranger. There was an example in this wired article about giving a woman a bouquet without telling her why or getting her permission and then walking away and saying, oh, I made her day and the woman objecting later, like you made me look sad and I'm not sad. I didn't want your bouquet. I don't appreciate this. It seems like they're just more trying to create content and get their own attention and if you're using people in that manner, it's not like you said it's not illegal but it's like not not cool basically. You don't have to exercise every right you have all the time.
