I have the same issue with regards to staying anonymous. It is really sad that we still live in a society where this is necessary, but that is just the way of things. I work as a freelancer and I am sure that some of my clients wouldn't want to use me if they found out more about my private life where others really wouldn't care. Elle, my Wife, on the other hand, has a job with a lot of responsibility. She handles confidential information and only has a few more promotions to go before she is in charge of everyone where she works! (Which she doesn't want lol.) There is absolutely no way that we want to be identified so I make sure that no personal information is given out at any time.
I do write about vague details about what we are getting up to but, if you are able to identify us by knowing we were skiing in Austria the week before Christmas and we are currently in England, then you are definitely the new Sherlock Holmes!
One of the things I advise my clients about is how to manage social media. This means how to use it positively with things like Twitter and Instagram accounts, but it also means how to keep private information exactly that, private. Also how other companies and prospective employers use social media when they are looking to work with or employ someone. I have also been involved in cases where children have been identified through their idiotic parents use of social media and have been put at risk.
It's one thing when a kid makes a mistake when using social media but, when it is their parents, that makes me angry.
