If you want to see the quality of his character then just look under his trust comments. Unless he has any kind of actual, concrete proof, I would think that he is just a disgruntled gambler who lost all of his money because he could not stop himself. Or he did something against the terms of service of the online casino that he is referring to (I am not going to quote the name).

He should know that accusations without proof could be considered libel/slander. Venting frustrations can become problems. Thats why adults don't act like this.

But on the internet.... Who knows how old somebody really is in real life.
