3taps isn't a client application for Craigslist, they essentially turn CL's data into a feed and then sell it to folks who then create services on top of that data.

Padmapper is a client of 3taps who's been the client app that most of this is focused on.

BTW 3taps doesn't scrape CL, they actually pull CL's data from Google's Cache so they can't be accused of violating CL's TOS.

Yeah, it would be futile for CL to go after Padmapper, so they are going after 3Taps. Why would they be more worried about 3Taps? Because anyone can do what 3Taps is doing. Anyone can pull CL data from a search engine cache like 3Taps does. There's no need to go to CL.

But one thing we know, if you look at the precedent, is that you can't sue Google and win. You either let them copy your site or opt out and lose the traffic. So what can you do?

Sue Google users! As far as I'm concerned, that's all 3Taps is. They are just aggregating what they pull from the cache.
