Well I got a mail from a user on Ricardo( the mail was from Ricardo). Said he wanted me to cancel my add in Ricardo and that he would pay a very good price for the artikel-an iPod- and that I should give my bank details so he could pay me. Then I should send the iPod to Nigeria. He was very persistent. Well I knew it was a scam-reported it to Ricardo and they confirmed my suspicions and blocked the User.
TIP: do all you dealings over Ricardo as then you are covered when something goes wrong.
