I noticed that Padmapper does a fantastic job of filtering out too-good-to-be-true (scam) posts from Craigslist — where the listings still exist on CL, but not on Padmapper. I'm not sure if it's just a function of import time (new posts on CL are far more likely to be scams and could be flagged before Padmapper imports them), but I'm calling it a feature for now.
