Who is untouchable? If you give your phone number, postal address or any information to a third party (and by third party I mean any website you sign up to, any competition you enter etc etc) without reading the T&Cs then you are liable to get these sorts of messages! Makes me laugh the time and effort you've gone to write this blog post when in reality it would have taken 0.000001 seconds to delete the text message! Viva la revolution! Long live the SMS spam!
