Most of the time the player turns out to be wrong and is using the forum to strong arm a casino. I still always start off taking the player's side until the book proves him guilty.
Bravo! But in the sincerity of my experience, this must be in rare cases unless you are not referring to this forum. It happens both ways as there are some casinos that will be easily sided and exonerated but there are even more complainers that win the casinos. Some cases were resolved, while others were never resolved even as most casinos were unable to prove their guiltlessness.
Owning to this, contrary to your claim, since I started reading cases between casinos and the customers, I give it 10%/90% won cases in the format of casino/complainers. Regardless, I advise everyone to start or continue their casino's journey with a casino with a good track record. This is the only way to avoid issues like this.
