As a consequence, we are faced with a problem of creating multiple accounts by the same user and abusing faucet (faucet at our site - 0.007 mBTC and only request every 3 hours when balance is zero).
Guys, what solutions do you recommend?
Thank you!
There are a number of things you can do:
1. Reduce the faucet amount, if you don't want to remove it altogether. It really doesn't make sense to me why someone would bother abusing0.007 mBTC faucet every 3 hours because honestly that's a very low amount.
2. Same IP detection, at least makes the life of the abuser harder.
3. A week long wait before a person can claim the faucet.
4. Some sort of 'level' program that increases the faucet as you gamble more funds. People who don't gamble get a very low amount.
