Could someone (@dang ?) fix the title please? It is /etc/shadow , not /etc./Shadow

There's a reason for this - having /etc/shadow in the title breaks searching from Algolia search due to a WAF.

eg try this

https://hn.algolia.com/?query=What%20We%20Do%20in%20the%20%2...

That’s so depressing.

That WAF needs to be tuned. If they’re worried about the possibility of a local file read that can disclose /etc/shadow, there are much bigger issues.

...that's a Cloudflare security page. Is this a default setting for one of Cloudflare's security options, or did Algolia specifically add this to some edge detection worker or something? I'm curious which party is being ridiculous.

I just hit a website I know has an entirely default config on the free plan as https://website/q=cat /etc/shadow and got the same exact error page.

So much for CloudFlare's stance on free speech, I'm being censored for comedy!

(The title is a wordplay on What We Do in the Shadows.)

Joke aside, I can understand why, generally, protecting from /etc/shadow disclosures is a good default, but it should be possible to disable this particular protection. If anyone knows how, that'd be good to share.
