Social media question

With everyone taking videos and filming how do you protect your privacy sometimes you don't want to be filmed. With social media and influencers and people who are taking videos through the day making content how do you avoid being filmed?

There's this thing creeps do

There's people who will pretend to take pictures of themselves like a "selfie" but are actually filming you have the camera facing towards the public not themselves

It's pretty obvious if they position the camera to follow you in the direction you move they follow you with the camera turn body towards you aim camera your way and it's rude and I wanted to know how do you get out of people's videos and pictures
