Jump on a plane and come over here Peter i have a nice house in Hua Hin just right for a Russian family just round the corner from immigration which is already full of your countrymen pushing in front of me with their agents.
Over the years i have known of farangs who end up losing houses over this problem, one friend of mine his wife got millions in debt and eventually she killed herself. They just dont know when to stop. You need to crack down hard and stop this (good luck with that) or walk it will end in tears and deep debt or worse.
