Gambling using fake money will have no responsibility in every betting session because the fake money that is bet can be added again and refilled,
Well, its credit is zero and there's no value on it so obviously there's really no need to be responsible upon using it as it's a feature of the casino where it can be found.
On some fake gambling game your funds are still limited and once it runs dry, you need to wait for some time again in order to get a play money. What if other sites or games which offers fake gambling copy this? That way players will need to treat their play money like a real money.
If you use bots for betting then it does the job for you. You wouldn't waste any of your energy or your time because you can just leave it running while you do other things. It's also possible to meet other people (real people) and not bots because a lot of these fake gambling games are online. This makes the game more fun because you can tease other players.
