some faucets owners doesn't care on what ads are being advertised as long as they pay them money. I've seen Ponzi sites being advertised in some bitcoin faucets.
If a faucet owner is using an ad network (e.g. a-ads, adbit.co, beeads, bitclix, etc...) to serve up ads on their site, they don't
necessarily have direct control over what ads are being served. Some ad networks have *some* parameters than can be set
(e.g. don't show any adult ads), but it's not like the faucet owners can pick and choose which ads get served to their site and
which don't.
For anyone that uses faucets - *most* of these faucets are run by regular folks just like you and me. They are funding them
out of their own pockets and
giving it away free to us. The least we can do to thank them is click on a couple of ads on their
sites.
I run two faucets myself, and I can tell you that my daily ad revenue doesn't even come close to covering even half of what
I pay out on a daily basis. But whatever income I *do* get from ads goes right back into the faucet.
