Everything that you post or gets posted about you (or that you get tagged in) is public knowledge unless you do something about it. Review apps that have the ability to post and remove the posting ability for those that don’t need it. Dont add your location unless its relevant and tag other people without their permission and ask them to do the same for you. Interest-based advertising uses cookies and metadata from other sites. Predators are lurking to abuse any information that you give them.”]
