It makes me deeply depressed that real estate is huge right now, many more people than ever are renting and we still have to deal with Craiglist scams to find a place to live. Ignoring the fact that the last ten years of UX seems to have passed Craiglist by, it's unbelievable that such a huge site has the absolute minimum of fraud prevention. There are so many comments on here about various kinds of CL scams, why does a trusted marketplace for rental housing not exist?
