I tried to sell an item on Craigslist and received a fradulent check. Please help!?

Craigslist clearly states that the site is meant for CASH ONLY, person to person transactions. NO shipping, NO money orders, NO checks, NO wire transfers. Perhaps you should read their disclaimer page. You can tell people about it all you wish. Perhaps you can convince the police to be there when the 'mover' arrives - but I doubt it. But that only takes down the 'mover'. The rest of the fraud ring is still in action scamming people every day. The police have better and more important things to do than wait around and arrest people over internet scams. At least you recognized the scam before getting scammed,which is good. Actually, no 'real' crime was committed - what would the police arrest the 'mover' for? What's the charge? He would say that "I am just doing a job that I was paid to do". It's up to internet sellers to be wary of scams - not the police's responsibility. Otherwise, the PD in every major city would be knee-deep in handling internet transactions gone bad every day, instead of dealing with things like murders, drugs, and domestic violence. The police already have their hands full. It's not like they have infinite resources to deal with everything that happens.
