Yeah this is one of those things that hurts some real users and AI scrapers have figured out how to bypass. Not worth it IMO.

How do you figure it hurts real users? The amount of compute/energy used on the proof of work is pretty minimal. You're using more when you watch a YouTube video or browse a JS-heavy web app.

Of course a sophisticated scraper can "figure out" how to bypass. It isn't trying to be foolproof, it's adding an extra cost to deter massive amounts of bot traffic.

I put it in front of my hobby project because I can't afford to serve hundreds of thousands of bot requests from residential proxies all across the world, and I didn't want to route all of my traffic through a third party company like Cloudflare.

I've been happy with Anubis.

		There are false positives. Every time I've used a tool like this, I get reports from my users about it blocking their access. It's especially bad for users who use privacy oriented browsers like Brave or use VPNs. For a personal site where you don't care about 0.1% of your users getting blocked, it's probably fine. For a business, blocking some of your paying customers isn't acceptable.
