Pro faucet farmers....really. have they ever been caught? I am not sure of faucet worth trying hard to hit 50k. Even if some hits that 350x one time each day. He will only make 0.015 btc per months which I think is not big and there are many chances that he won't make it even half of it. And none have that much patience to wait for it whole day. It's nothing in front of what primedice gives in it's giveaways.
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?
Yup.
Both of you are missing that robots can farm the faucet automatically while changing the IP every once in a while to continue farming.
The only real way to protect themselves is to lower the amount given by the faucet so that it's no longer interesting for robots to do it.
