I've an question, I've seen a lot of cryptocurrenty faucets using Adsense, but is it legal at all to put Adsense in that kind of sites?
Coin url , Bitmedia , A-ADS is better to faucet web than Google adsense
Unfortunately those sites pay you next to nothing compared to google adsesnse, that's why people use it. If google doesn't ban then, it is not our problem to fix. It wouldn't be profitable to run a faucet otherwise.
