I recently wrote a review on Trip Advisor and have received a question from someone. I think it is worded in a strange way and wondered if it is some sort of scam (ie, if I reply they can get some sort of information about me). Any ideas? (or am I just being paranoid).
They can't get to know anything which isn't or on your public profile (or, of course, which you choose to tell them).
