Why can't CloudFlare assist with the DDoS attacks?

I have only been mining for a week or so. I enjoyed the CoinEx site quite a bit when it was up. When it went down I took a recommendation to mine at the MiningPool.co. I have been mining there for FST for about two days now and my avg KH/s is 2781, Estimated avg 1330 coins.day my actual mined last 24hrs 625 coins. Am I missing something? The highest Difficulty for the past 24hrs was about 1.6. If i use that difficulty in a calculator with my avg KH/s rate I still get 1118 coins/day. seems like there is about a 55% pool fee in there somewhere.
