What I found is that blocking completely works less than just delaying the page for a bit with something like https://chrome.google.com/webstore/detail/waitblock/kcnjfepp...

That way I have enough time to think and question whether I really want to open the page I was about to open, and I don't disable the whole thing if I actually need to visit it.

My favorite is: https://chrome.google.com/webstore/detail/go-fucking-work/hi...

Thanks for the recommendation, but why is it a subscription service? Does it work like a vpn or something where they host servers to support this kind of traffic blocking?
