SWOOPO....Via Megan McArdle, this has to be seen to be believed. Swoopo.com has been around since 2005, it's almost literally a scheme for throwing money into other people's bank accounts for no special reason, and apparently it's still going strong. Details here.
At least Bernard Madoff's customers had the excuse that they didn't know what he was doing, but Swoopo appears to be pretty upfront about the whole thing. There's no excuse for not realizing what's going on except rank idiocy.
