Was doing some research for my book.
Here's a guy called Justin Credible that rips off a Nigerian trying to rent a room from him on Craigslist (from 2005). He incorrectly assumes the person sending him a check is a scammer (hint: scammers don't send you money). Worse, he thinks he is smart. The guy is a crook. Frankly, if he didn't like the sound of transaction (it seemed risky given the potential that he was laundering money from an expense account), he should have ignored it.
