2. If you see them getting ready to take your pic hold up your hand to block your face. Slightly show your middle finger. When they report you for doing so, just say you were blocking your pic from being taken without your consent.
3. Report to ethics point/he (I think that's what it's called) they should put a stop to it. Be cautious of retaliation that may come your way.
I found two pics of me on a Kroger review page. I am at the time clock-they are side views. Taken without my knowledge 5 years ago-I just saw these recently
