Keep things to yourself
Stay as anonymous as possible on the net. False names, disposable e-mail addresses, etc; are the order of the day where ever possible. Never publish an identifiable picture with real humans or their faces visible in it, hard though it may seem to be for some social media addicts to do - or better still, don't use that invention of the devil at all. I never have indulged in so-called social media and never will. Airing dirty linen in public and laying one's soul bare for all to see is sheer folly these days.
