I don't have the time to keep this faucet and haven't been managing it lately. It works with wordpress, ads are easy to manage, has many captcha options, uses faucethub. Lots of statistics and options on the backend. There's even a newsletter set up that I've never used, but it's there. Security has been taken care of (I think I did more than I needed actually, since I never had any problems with bots or anything)
