They probably aren’t enforcing it because it’s only 200 sats which is like 4 Pennies. So with 20 accounts you don’t even make a full dollar. Not worth the headache really.
People used to do this with Bitcoin casinos like dice sites. They gave a faucet of like 1000 sats. And people would gamble with it to hit the min withdraw. Eventually people started to abuse it and they had to remove it.
