By posting, you're agreeing they can do whatever they want with your data and prohibit others from taking it from their site. Morally and legally, I think they are in the clear. There is no moral right to be able to scrape someone else's site and use their data because you want to.

I don't think they encourage people to scrape their data at all. They have a long history of blocking people and stopping people from doing exactly that.

Their data, their rules. It's not like Twitter where they pretended to be developer friendly and screwed over everyone. Craigslist was NEVER developer friendly. They were pretty upfront about it. PadMapper knew what they were getting into, even acknowledged they were in the wrong, and continued to do what they were doing anyways. How Craigslist gets portrayed as the bad guy is shocking to me.
