I used click any line anti-bot script on my faucet. I copied it from,
http://highcryptofaucet.com/It is more effective and less annoying than clicking 6 links.
FaucetBox (scanthebox rotator) and ifaucet would not accept your faucet if you are hiding claim button. Because of this reason now I am using Funcaptcha.
According to fun captcha stats, 1314 bots were blocked in the last 24 hours. I am using clicky stats for my faucet analytics and I have noticed that bots does not spent more than 10 seconds on my faucet and funcaptcha has indeed blocked these bots. I would suggest using 15 sec timer + funcaptcha for your faucet
