You wouldn't believe the amount of people that still fall for this, it blows my mind. I work in banking and get at least 15-20 people per week coming in with these letters trying to accept wires or cash checks they get with letters like this. What they want is for you to release your routing and account numbers so they can make the counterfeit checks like the ones in reverse's post. The worst one I've seen was a customer of mine that got taken for a couple hundred grand. Unfortunately he never thought twice about giving them his numbers because the amount promised was so big. All the withdrawals were made in a 48 hour period. The worst thing about scams like this on is that FDIC insurance does not cover this type of thing, so he had to pay us back the money from his own pocket. the only thing he could do was file a police report, but unless they catch whoever the funds went to (usually out of the country) he's stuck.
