It's even dumber than that, because by default anubis whitelists the curl user agent.

    curl -H "User-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/146.0.0.0 Safari/537.36" "https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/diff/?id=v7.0-rc5&id2=v7.0-rc4&dt=2"

Anubis' white lists and block rules are configurable though. The defaults are a bit silly.

The default is to allow non-Mozilla user agents so that existing (good) automation continues to work and so that people stopped threatening to burn my house down. Lovely people in the privacy community.
