Honestly, it probably would be beneficial to my productivity if I dropped all of Cloudflare's IP ranges since it'd keep me from going on HN, Reddit, etc. :P

The need for incentive you mention is silly. The website operator [much like a job searcher with a resume] wants to be in front of as many non-malicious people as possible. And while you might argue .04% of malicious traffic comes over Tor, I've operated sites where 20%+ came over some sort of proxy with poor IP reputation.

You know what?

Fuck it. I'll just build my own site that doesn't use Cloudflare for such a purpose.
