It is an issue on facebook certainly.
people posting information they may see as harmless when in reality it carries risk. It must carry risk making it more widely available.
it may be open-source but why give it out on a plate.
Everyone on here will have a digital trail of birthday, place of birth, wife's name, pet's name etc and we all accept that and do.our best to mitigate any risks to ourselves. All of this info is "out there" so if I understand this correctly none of you who cannot see the problem would be happy for anyone to compile that data and publish it in one place for all the world to see?
When the facebook aviation groups are challenged on what they allow to be published 99% get it and stop it from happening. There remains the 1% who are only in it for the clicks and likes and don't care about what the consequences could be, no matter how unlikely.
If it "could" help an enemy/terrorist/subversive then don't post it.
