There are literally bots that used to abuse the faucet, sure there is some prevention and I am sure there used to be a lot more and there are less right now (which is something we can't really calculate because if they are any good freebitcoin will not feel it, if they are bad freebitcoin will ban it).

However, back in the day we all know there were bots that literally changed IP for each account and literally had 50+ accounts all claiming faucet together 24 times a day (or if they are any smart 15-18 times a day) and made a ton of money from the faucet. Thankfully the "white hacking" or basically how to stop bots are better in technology and I hope freebitcoin doesn't have too much abusers but that doesn't mean they existed back in the day that ruined the profits of freebitcoin.
