Never mind the haters, and if you give in to them, you're going to spend a lot of time trying to address them, rather than running your faucet. However, every once in a while, when a user comes along and pleads his/her case of being innocent, it might be good to see instances where you can prove that they were using proxies or VPN's, just to provide us legitimate users with peace of mind knowing that you will pay those of us who use the faucet as it was intended.
Keep doing what you're doing, admin, and as long as you continue paying out your honest users, this will soon be a very popular faucet
Here's a couple of recent bans. You can locate the IP's if you would like, I had to block one IP for security reasons. http://puu.sh/oV46O/0ce8b54ebe.png and http://puu.sh/oV4dZ/ecdffe0f9e.png . Our list of IP changes isn't organized at the moment so I just pulled those for now. Also if you don't know, I assisted in making the site.
