Latest nightly builds of Firefox 139 include an experimental web link preview feature which shows (among other things) an AI-generated summary of what that page is purportedly about before you visit it, saving you time, a click, or the need to ‘hear’ a real human voice.

Overboard? Because I disallow AI summaries?

you disallow access to your website, including when the user agent is a little unusual. do you also only allow the last 1 major version of the official versions of major browsers?

yet, those rules are responsible for stopping about 2.5 million requests per day,

you disallow access to your website

I do. Any legit visitor is free to roam around. I keep the baddies away, like if I were using a firewall. You do use a firewall, right?

when the user agent is a little unusual

Nope. I disallow them when the user agent is very obviously fake. Noone in 2025 is going to browse the web with "Firefox 3.8pre5", or "Mozilla/4.0", or a decade old Opera, or Microsoft Internet Explorer 5.0. None of those would be able to connect anyway, because they do not support modern TLS ciphers required. The rest are similarly unrealistic.

nepenthes. make them regret it

What do you think happens when a bad agent is caught by my rules? They end up in an infinite maze of garbage, much like the one generated by nepenthes. I use my own generator (iocaine), for reasons, but it is very similar to nepenthes. But... I'm puzzled now. Just a few lines above, you argued that I am disallowing access to my website, and now you're telling me to use an infinite maze of garbage to serve them instead?

That is precisely what I am doing.

By the way, nepenthes/iocaine/etc alone does not do jack shit against these sketchy agents. I can guide them into the maze, but as long as they can access content outside of it, they'll keep bombarding my backend, and will keep training on my work. There are two ways to stop them: passive identification, like my sketchy agents ruleset, or proof-of-work solutions like Anubis. Anubis has the huge downside that it is very disruptive to legit visitors. So I'm choosing the lesser evil.
