it's a common scam which take advantage of Skype services. Well you can report them to firstname.lastname@example.org so they can check and investigate the activities of that user, and possibly block them if deemed necessary.
I have been contacted by this scammer pretending to be the General. They have also contacted me using the name Sir Alexander Richard David Sherreff and also General David M Rodriguez (skype name gen david.rodriguez878) What always gives them away is the poor spelling and grammar.
I have had 5 such messages since yesterday. Is there any way to stop them??? It seems the more you block and report, the more messages you get!!!
