Kyle Taylor reached out to me on Slack and worked with me to get setup on Cloudflare.
As of a moment ago I am setup there ($20 plan) and he wrote some blocking rules. Will see how it looks over the next week.
He did this with me a sort of a guinea pig to help update docs so that others can more easily do it on their own.
I will post back here to let you know how it works. I will create my own Google doc to show you my settings.
The only glitch in moving over was it took 15 minutes or so for the SSL to get up on Cloudflare, so site was down then. Probably there is a way to pre-provision that.
