@Mark116 - I was fairly sure it was a scam as there is no legitimate reason for a guest to want to communicate outside the platform. I say fairly sure because I couldn't be certain so went back with a simple 'Happy to answer all your questions through this messaging facility'. If it was honest then we would have continued without a problem.
Now when I logged onto the community centre I find a near identical message being discussed so it confirmed the scam. My guess is that it would have turned into a 'lets split the payment' scam using a stolen credit card.
@Helen350 I've reported the profile as per your instructions so hopefully, if everyone reports people quickly, we can stop some less suspicious host being scammed and losing their money.
