A players balance belongs to the player.
To a legit player that didn't trigger the abuser matrix.
If they triggered the abuser matrix, the balance is dissected, and whatever was the casinos money before, is back to being casinos money.
You have to understand that there are millions of forums, scripts and subs dedicated to scamming operators, who are bombarded with them on a daily basis, and dealing with each and every individual case takes resources, and you're either large enough to have those resources, or you go through the route of ignoring them.
You mean if they really wanted to steal players money why did they only steal some and not all of it?
Because that's what scam casinos do. It's called a freeroll.
Technically, the casino didn't earn any money on this if it was a full refund (house edge/vig included), the total revenue on that player account are now zero.
Your list should read:
#1. Coinplay and player had a dispute of players balance.
#2. Coinplay and player agree to use third party.
#3. Third party rules against Coinplay.
#4. Coinplay still doesn't pay player and ghosts the forum.
This is true. However, I think that there's more to this case then we see here, but there's no way in finding out that info, so we're just wasting our time arguing.
