I have been told that new recently posted ads in Craigslist typically get contacted by scammers look'n to hit on a newbie ...... so's you want to be a detective for possible scammers posing as a buyer .... and use your best judgement with WHOM you choose to communicate. ...
Years ago, a scammer could purchase a bank check for $6.00 ..... and then alter it with a fountain pen to turn the $6.00 into $60. and use the altered check to purchase some item that cost $25 from someone who was eager to sell the item plus give them $35 in change.
