There is a scam wave coming from Mali and Nigeria in many places, you can find this on all websites that sells from Asia (China specifically) and forums and classifieds) in Middle east. They even post on ebay.

I have dealt with those scammers many times up to the point that they called me pegging to send the money and swearing to god that they will send me what i am looking for. i have not been scammed so far, but who knows there is always first time :)

These scams relies on basic things

1- Very attractive deal (good product for low price). greed, lucky feeling, and sometimes opportunity to make money out of it by reselling.

2- trustworthiness, as they provide suspicious offer by sending money before you get the item, they ask you to send it to another name and detail but send them a scan for the transfer for their assurance of commitment from your side.
Western union only requires tracking no. and they will cash you the money instantly, regardless to whom it was sent and to which country you sent. if you sent it to UK, they can cash it out in Mali or Nigeria.

qatarliving admin or support cannot monitor every single posting for validity or scam, same as it is for ebay. They can only act if it is reported. every post here has a report scam / fraud button that you can use to report the post as scam.
