"One of the things presented to the jury was a review of different html codes for Web sites. The eBay Web site html code told robots -- such as BoatRover -- to keep out while YachtWorld.com's code welcomed robots and told them to come back in 30 days, Conwell said."
Interesting story. Based on the quote above, I'd say that the legal team needed an SEM on board to explain to them what is going on.
It sounds like they are referring to the robots.txt file in one instance and then the META revisit tag in another instance. Unfortunately the META revisit tag is not supported by any major SE. In fact, it is specific to one particular SE (SearchBC).
