Hmm for the oneminute faucet I think the average of 50 satoshis is a little too low, minimum should be 75-100, since the users cant exactly claim at 1 mins intervals given that they have to refresh the site.
Hope bitworld comes back, and also the rewards stated there mismatch the ones stated here.
Saw a popup there too, maybe you should remove it, because users would dislike it.
