I do not remember what theQuin mentioned about this but there is no way you can go below 1 SAT. The minimum value is 1 sat as bitcoin cannot be further divided. I think freebitco can only limit the per hour free faucet to perhaps every 2 hours or so. They need to apply other tactics if they think 1 Satoshi per hour is too much for a free faucet.
It's true that 1 sat is the smallest unit of bitcoin and you can't divide a sat to smaller units, but there's nothing stopping a centralized service like freebitco to have smaller units than satoshi.
Welp, i just submitted a withdrawal of my funds from the site to my wallet. The site says it's gonna be sent in about 6 hours.
You should receive you fund without any need to worry about it.
Although there are some issues going on with the service, I haven't heard of any issues with withdrawals, recently.
