What if instead of proof-of-work we made proof-of-leisure
As scrapers click on everything they see sporadically without any sense or reason, they won’t wait for any amount of time when they get to a website - they will start to click every link they see until the whole bandwidth is wasted on their stupid bullshit.
What if when some website is opened for a first time from that ip/useragent combination there is a page that says “do nothing for three seconds and don’t press on any of those links” with 5 faux links that will immediately result in being banned. Then after 3 seconds links disappear and the original requested page opens up.
Is this something? Maybe even 1s is enough
