Creating hundreds of accounts as the referrals of one master account my friend. It wasn't that hard to find out C'mon. I know it doesn't make sense to you but there are people abusing this. freedogecoin is no more because of that.
How do they track it down? Is there any system to detect possible abuse of their program? If someone uses VPN services with more than 10k IP addresses managed each day, note down the IP and name of account used to login on that IP and only login when they get that IP back, how will these guys outreach these kind of abuse? Is it legal if someone has 100 devices with 100 static IP addresses and they use the faucet with a single master account and all others under it as their referrals?
