I run a similar audio-heavy site [1] that's reached the front page of HN, also behind Cloudflare - the traffic spiking to terabytes a day is a bit of a shock at first but if everything's configured properly CF works well
FWIF if you are looking for a decent alternative take a look at ModSecurity project by OWASP.
My main problem with it is that we put all websites behind a single point of failure. One with large corporate interests. It is the antithesis of the free and open web.
Also I dislike it from a technical standpoint. It makes response times from the server much worse. And I spend a lot of time improving the performance of my sites, to throw that all away because I’m afraid of hackers seems like the wrong solution to me personally.
SSL added and removed here :)
