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?
Pretty sure the guy just made a few accounts himself and probably didn't bother with the VPN route. And even if he took the time to go with a VPN it's not that difficult because he basically all had them linked to a single account.
This is the reason why many sites no longer offer actual faucets because of abuse like this. A few years back there was very little faucet abuse and I remember some sites would give you like 3000 sats for each faucet claim. And then 2017 rolled around and people started to get clever and basically ruined bitcoin faucets for everyone.
Hence why most sites just offer some demo or fake token plays and instead of faucets they got promos for the genuine members.
