It’s a clever solution but I did see one recently that IMO was more elegant for noscript users. I can’t remember the name but it would create a dummy link that human users won’t touch, but webcrawlers will naturally navigate into, but then generates an infinitely deep tree of super basic HTML to force bots into endlessly trawling a cheap-to-serve portion of your webserver instead of something heavier. Might have even integrated with fail2ban to pick out obvious bots and keep them off your network for good.
