Never publish your date of birth online, this allows you to be located by using tools such as the electoral role when combined with knowledge of your locality which is often given away by geo-location tags on social media such as facebook. Unless you think you would require the use of a birth certificate or other formal identity document to gain or re-gain access to accounts or services you only have to prove you are so-old so make a different birthday, maybe 1/1/1978? something easy to remember.
Don’t forget – a surname, date of birth and an electoral role can be a direct match!
