Be careful when uploading photos onto your social network. The photos usually contain geolocation data and other data that may identify you and track the places where you took the pictures. Also, be cautious about how safe your content is on a social networking site. Never rely on a social networking site as a primary host for your content or information. It is very easy for governments to block access to a social networking site within their boundaries if they suddenly find its content objectionable. The administrators of a social networking site may also decide to remove objectionable content themselves, rather than face censorship within a particular country.
