If the faucet is really to allow someone to try out the site but not to cash in, why not add play tokens instead?
Because no one want to play with worthless tokens.
The way they have it now is misleading and only suits to trick users into playing there, and fluffing up bitslers user and bet statistics.
That is why you have to read terms of service and if you don't like it you can always choose to play elsewhere.
Seriously, read ToS.
