Or you could increase support staff?
Why should they increase the amount of support staff they have so that people can leech faucet?
Because those leechers you are referring to consists of 70%+ of the community. Question, am I a faucet leecher when I have deposited 0.2+ BTC but uses faucet a lot? Also player X faucet faucet faucet 100 times, gets sick of it and deposits 0.01 or more (for example).
By faucet leechers I am referring to those who are only here for the faucet rather than to gamble and spam support emails when they can't cash out dust.
