A lot of sites will be running the miner at lower settings so not to overload the user cpu, consider things like these before you go on a witch hunt.
People whine when there are too many ads, people whine about popunders, people whine about interstitial links, people whine about browser mining...
How are the faucet owners supposed to finance the faucet you're claiming from?
I think you are out of topic. We are taking about faucet that run the miner without user consent and i guess your site is one of it (correct me if im wrong)?
I agree with you that a lot of sites will be running miner at lower settings but most of it also mentioned this on their site and share the profit mined.
If you are solely or mostly profit from miner then I don't think your site will sustain for long.
Go look for better ads network or perhaps you can put few more banners on your site. People don't mind to see few more banners than having to run the CPU because not many people has powerful CPU.
