Cuil isn't around anymore, so I see no reason why it should be in the list.
Short and simple.
Any reason why it shouldn't ?
Cuil is dead. It's no longer a search engine. It shut down 8 months ago.
How is any site going to be crawled/indexed by it if it doesn't exist?
I guess that's as good a reason as any
Their servers were shut down, so no, the crawler can't index anything.
