Hi mate I had this done to me with my Nokia phone, its a Nigerian scam, delete bids immediatly. They bidded on my phone for 650 quid was not worth 200, They then asked if I would send phone to Nigeria, as it is for their partner. They slowly get information from you, I.e Your full name and address through asking several questions via email and phone. they will say they will send you a cheque as proof they want to buy and will ask for your address. They will send you cheque but cheque will bounce. then they say they will do a bank transfer to save complication and ask for your sort code and account number which is harmless as appears on all your cheques, but then bingo... they have now enough information to withdraw large somes of crash from your bank. All they need is your full name billed address, bank details, and somehow the bastards can rip you off alot.
I learnt from this and did what one clever guy did and asked for pictures of them holding up signs to you. I got someone to send a picture holding up a card which I told them was a greek word for honest which was ****. and guess what the stupid idiot did it, does not solve the sale, but is bloody hilarious at their expense
Delete them and put at the bottom off your ad: not racist but please no Nigerian scam artists, your bids will not be tolerated. It will act as a deterant.
