I agree with you that it is infact a DDOS protection but still, the fact that it is open source and created by a really cool dev (she is awesome),
I think I don't really mind it gaining popularity.
And also they had created it out of their own necessity which is also really nice.
Anubis is getting real love out there and I think I am all for it. I personally host a lot of my stuff on cloudflare due to it being free with cloudflare workers but if I ever have a vps, I am probably going to use anubis as well
It also doesn’t cede more market power to CloudFlare, which tends to block non-mainstream browsers, users with adblockers, Tor, or cookies and JavaScript disabled.
This tool does block JavaScript-disabled browsers though. There's a comment here that complained about the pain Anubis causes with cookie-less browsers, but they got downvoted.
IP reputation will be subject to very high false negative rates because some unscrupulous bots have taken to laundering their traffic through residential proxy companies. There are alternatives to cookies like Etags, but they have their own issues.
