Last night, I got approached by an entrepreneur friend of mine over Facebook chat. He said he was mugged and robbed on a concert tour to UK, and currently in a public library in Cardiff, Wales, to where he headed after the robbery to ask for help. When checking his profile, my friend had posted concert pictures from LA a week before. I really thought he was on a global concert tour. I was initially cautious, but wanted to help. After a few moments of chatting, I was pretty convinced it was my friend. He asked me to send him cash over Western Union. I checked the online payments from Western Union to help him out, but it was not possible to send money online in this case. He asked me to go to nearest Western Union office to send the money, but at this point I was starting to get curious. I asked him to send me his wife's number, so that I can call her to announce the incident. The guy on the other end had a good excuse not to. He even sent me email to my email address without asking for the email from an email that was in the same format that my friend was using, but possibly not his email. The email even had a UK phone number that he claimed to be for the hotel manager in the hotel he had been staying, and asked me to verify him from there. After consultation with my brother, I decided that the guy on the other end may not be my friend after all, even though he knew a lot about my friend's doings. I decided to ask him a question an outsider can't answer: "Where did we meet the last time and what did we talk about?" - the guy on the other end excused himself, saying "come on, I am mugged and bleeding and in need of help and you suspect me?" and other stuff like that. I insisted him to answer my question. When he did not, I said that he is a fraudster and I will call the police. The chat closed immediately after. This was a cleverly planned and prepared fraud attempt, with the other party actually chatting with me, knowing a lot of stuff about my friend and me. How did he know all that? He got it from our Facebook profiles! I am sure many people will fall into such trick, since they appear legitimate and highly realistic. Facebook and officials must cooperate to get these scammers caught before they cause too much damage. IF YOU GET APPROACHED IN A SIMILAR WAY, PLEASE MAKE SURE YOU CHECK THE AUTHENTICITY OF THE PERSON WITH HIGHLY PERSONAL QUESTION THAT CAN'T BE ANSWERED BY LOOKING AT THEIR FACEBOOK PROFILES.
