FJ gives faucet money only to play a dice game and for other games, they don't give faucet money. But we never hard that anyone accounts are banned or withdrawals are withheld just because they didn't deposit money.
AFAIK FJ gives fortunejack coin or for free play money instead of faucet? I played on the site long ago and I did check that they still have the free play currency there. Not sure if they actually give real faucet to players right now or now
In my above post, I already said that they give faucet money only to play dice game. If you want to try other games then you should play with play money because for other slot games they won't provide faucet money. In a dice game, they give free real money and if you can make a profit out no issue but it is quite hard to reach the withdrawal limit from faucet money.
