The best online casino sites are cautious about potentially fraudulent customers to the same degree as gamblers are cautious about potentially scammy casinos. Online casinos can be perceived as a good place for money laundering operations, and criminals can try and process the money associated with illegal activities via betting platforms. This is why casino sites take an effort to identify and verify their customers.
Besides, online casinos need your personal data to have the right to accept money from you, and to pay your winnings out to you, too.
