Craigslist doesn't make any money from those scams because they don't charge for rental listings. It sucks that it's there, but for them to hire staff to deal with it, they'd have to charge for the rental listings. Right now they rely on volunteers to combat that problem, in the form of legit landlords reporting the scams.
So why not charge for rental listings? i'm sure the number of scams would go down, while posting would still be of good value for someone looking to rent out a $3000/mo apartment.
Have I gotten a bad deal a few times? Yeah. Would I have gotten a better deal elsewhere? Unlikely.
Consider the thesis of the "craigslist is sketchy" argument the next time you look something up on Amazon and the first 3 results are from WODBEP, QXJEFN, and PLUDJ.
IMO the thing that actually spooks people about CraigsList is interacting with strangers, but Facebook isn't better. If you're stalking someone's FB because you want to buy their old TV, well guess what, you're the creep, not them.
