About the withdrawal limits we have it placed so people could withdraw once in a day instead of withdrawing after every claim and also we limit it because we have more than 90k users on the site so everyone can get their earning everyday.
If you set a withdrawal limit that's reached in less than 6 claims, then it doesn't matter whether you allow a withdrawal after every claim or not, users will not claim from your faucet more than 5 times a day, simply because they cannot cash out more than what they get in 5 claims.
What sense does it make, having all users leave after 1:15 hours?
