In fact you wiped out all referrals that users had and reduced reward to 1000 satoshi?In my opinion such a drastic change is not good,but this is your faucet so it's your call.
I have a backup of the database if I ever decide to revert back, all the referrals would be restored, I will keep the faucet like this for a week and see how it works. The reasoning for the changes was as follows:
Reduced Rewards = Bots were making me lose over a million satoshi in less than 24 hours, half the reward will mean half my loss.
Removed Login System = I had 600 registered users, but when I checked the database, 10000 different address had claimed from my faucet. (600 accounts and 10,000 addresses) So the login system didn't work.
Changed To Solve Media = Solvemedia acts like an ad, so when proxies block ads (that faucetbox can't detect) the captcha won't show up.
Removed Most Of The Ads = It was still looking cluttered to me, and positioning is very important with ads.
