I did something like this a few weeks ago on my photography site: https://robertmay.photography/journal/meta-has-tried-to-scra...

Meta not only hasn't noticed, but is currently sending about 11 requests per second to my site. I've also seemingly trapped one of those TV proxy scraper nets as I'm getting absolutely hammered by requests from all over the place now. I get maybe 10 legit visitors per day, and I'm currently blocking 406,787 IPs from things that have fallen into my honeypot.

I've tweaked my site to return empty status responses a configurable amount of time but the traffic has been so intense that Traefik is now struggling, so I'm going to have to figure out something else. I was returning over-capacity errors and I think that was a mistake, I've swapped to 400 range status codes now. I don't want to use Cloudflare so I'm not sure what to do after this.

The people at these companies are either incompetent or malicious.

Return a HTTP 301 pointing to https://facebook.com?

Might make them scan themselves instead.

Since it's a photography site, route 'em over to goatse. That might get someone's attention.
