As some one who is doing some faucets in last month, I'm telling you if I can't withdraw when balance is 100 k satoshi I simply move on.
If you want to be successful you need to lower withdraw amount to 0.001B.
Just telling what I think and act upon my thoughts, as your way of faucet claim site is only short time profit, for long term you need to adapt to the clients(noobs the faucets claimers like my self ).
