ya of course we have already so much suggestions ;p

1. is this possible to see the user have most claim per day/week/month ?
if yes, then we can reward our loyal users (lol)
for that user most have referral too

2. Country Tier ! you know usage, no more explain...(need script)

3. and the Final Suggest..(w0w); we can use that sht bots! just we pay minimum satoshis to those, like 1 or 2 satoshi per claim !
better than ban them at all ?! (:-o)
(how can this work? just u know!)

don't know these 3 card is good for play or not, feel free to add that all to your project :}
