All bitcoin faucets are scams. They either promise 1 million BTC in 10 seconds or they give you 0,00000000000001 BTC which they won't give it to you until you make like 0,1 BTC ( good luck with that )
It's because they want to want to know if it's actually you who is buying the bitcoins. Example: You could buy a stolen card from the darknet and and buy BTC using it then the bank would issue a chargeback and then the bitcoin seller is screwed. That's why they ask for ID.
