Full title: I hid a link on my website that only bots can see and told them not to follow it. They broke the rules and in 4 days they went 124,414 levels deep into an endless maze. One bot opened 782,580 doors. I thought this was super interesting, this is how the internet is these days. Thought I’d share.

So what you’re implying is this should be implemented in every website in both follow/not follow just to waste their money?

I wonder if it’s possible to trap bots like this and use them to mine crypto.
It’s not. The bot just gets a copy of the website, looks for links, and then sends a request to the server to get those subdomains. Highly unlikely that there is a vulnerability that let’s you execute arbitrary code, which would be what you’d need to mine crypto.
I’m sure it might be possible but whoever would be doing this wouldn’t let their secret out.
