I personally see the Online Casino is the growing business as it is really convenience for player to sign up and play from their home. But as the number of player growing there are also a lot of fraudulent players who want to do whatever they can to make penny from Online Casino, of cause such as sign up multiple accounts to abuse Bonus, chargeback ...etc so I am wondering how does Online Casino detect fraudulent, what kind of sign and information that Online Casino looks at the first place to identify a fraud, and what would they do with that fraudulent account? Do Online Casino operators share each other their player information to find out suspicion accounts?
