Not only leboncoin, but ebay too. The 'purchaser' will send you a very good imitation of a Paypal transaction made in your favour, asking you to click on a link. A simple check of your Paypal account, not going via their link will show you that you have not been paid. We had someone that lives 15km away from us that tried it. When we pointed out to her that it was a scam, she wasn't at all worried that we realised. Generally, if someone offers to send a cheque, I accept it as it will be stolen and I would prefer that it went to someone that is aware of the scam, rather than an unsuspecting individual. Upon receipt of the cheque I take it and a copy of the emails to the respective bank for them to do as they see fit. Paper is an excellent item for obtaining fingerprints. When the 'purchaser' contacts me to arrange collection, I agree and tell them that I am easy to find as I live next to the Gendarmerie. Needless to say, I hear no more.
