I have no idea if it works, but Anthropic in particular spent a lot of time crawling the tar-pit[1] I had running on my domain. They were the reason I set up the tar pit in the first place, as they were at one stage averaging 5 requests per second, for days, on a blog site that probably doesn't even have a hundred pages on it. They've retrieved millions of pages of content from my tar-pit that were texts generated via markov chain from the contents of Moby Dick.
