Yes, I found that "safety limits" now... The faucet was going very well.
Faucets using this thing lose many users because everybody likes to complete the captcha and earn at least some satoshi, better than receive a "safety time limits" message. I think it's better to decrease rewards a bit too than receive that message and earn nothing.
I disagree. Just come back the next day. The safety limit is designated by the faucet owner to make sure he only pays out what he has budgeted per day, or to stop bots from draining the faucet. As this admin grows his sites, I'm sure he'll make changes to his faucet limits accordingly.
Admin, I've also noticed that all of your sites allow claims by users using AdBlock. You should make a script that requires that users turn off their AdBlock before they have to claim... Preferably with a screen popover that covers the screen and asks the users to turn it off.
