It does not really worry me. On here, my work website/facebook page anyone can find my face. What i do not do it post photos where others may/can take offence of what i do., eg my personal facebook page. All my friends know what i do, some come stalking with me, others do not and will not take the time of day to even talk about it. We all have our own opinions and im very happy to keep it that way.
If someone wants to find out who you are and where you live its very easy, a blurred photo will not make any difference to them.
