Should we sue softlayer.com to force them to stop crawling us?

Despite numerous attempts to get softlayer.com to stop crawling our site, despite phone calls and emails with log files, etc, they are still hitting FunAdvice daily more than sixty thousand times.

To put that in perspective, SoftLayer is the #1 consumer of content on FunAdvice, despite their not being an ISP, despite the fact that this is a no name robot, despite the fact that we have banned ALL of these ip addresses.

The court precendents are clear: softlayer will lose this lawsuit. The best estimate we have for lost revenue is 20% based on our initial analysis, to date...which means they have cost us well into five figures since this issue started.

Should we sue them? I don't think it's right to bring a lawsuit personally, as I believe that business should be conducted with ethics. However, when rational dialogue fails...well, that's why we have the court system, right?

I'll give them another 48 hours...then, we're finding a lawyer. Let us know if you know any good ones.
