Funny enough I can actually view their article.

Despite that I can visit websites where admins that set permissions not overly tough, I still run into enough blocks due to cloudflare that I'm considering investing time (ok for the last few years I've been really really lazy, I'm happy enough to copy and paste so I can manually write a nasty comment ) so that for each "bad load" the web site can be added to my disallow list. It might only save the smallest amount of wasted bandwidth but I guess it all adds up.
