It's definitely more than enough to stop me as a human wanting to visit the site, so yeah.

In that case a better solution would be to take the site down altogether.

Take down the site entirely because a couple humans get into a fit about it?

I'm just saying, making visitors wait at least a minute while making their device turn red hot is going to stop 99,9% of your visitors. So at that point what's the point in trying to serve the content?

The site's down entirely anyway. The silly "proof of work" finishes only to tell me the site is down.

What a waste of time.
