Looked at your blockchain page and there are a couple of payouts but it looks like you're not actually passing on the majority of the fee to the miners. You're only paying 0.0001 fee, but charging your users 0.0005. Is that intentional?
And it looks like the are separate transactions. Why not batch them up to minimize the fees for everybody?
Only a portion of the transactions are payouts for users of the faucet, and batch payments are something I can look into. It does look like a fee of only .0001 is being charged, even though documentation of the tool I use for the transfers says the minimum fee is .0005... I've updated the faucet to reflect this number and have changed the fee and minimum accordingly.
[EDIT]
The faucet has of the time of this edit made 6 payouts, and can be viewed at the block chain link at the bottom of the page.
