Exactly. I think setting a limit like no more than 12 registered accounts from one IP address would be enough to not worry about abusers ever more. Or am I missing something?
IP limitation was never a good option to prevent abuse of any sort. Using VPN or any kind of proxy will defectively render this security feature useless.
If the faucet farming is really that harmful to the site then the best way to prevent faucet abuse is to limit faucet somehow.
For example:
Faucet should only generate really low amount of satoshis, and grow over time with more wagered BTC.This is a good idea and something like this is implemented on Primedice, but unfortunately your faucet starts growing only after 10 BTC is wagered. I think it would be nice if we had at least a small addition to our faucet after say every 0.1 wagered. I mean even 1-2 satoshis plus to your initial faucet would make you feel that you are making some kind of progress.
Yeah but... I mean that's really not a priority for PD and I understand it...
Why bother giving things to very small players? They won't bring much money anyway :/
