Crashino isn't the only casino where the terms are like that for the inactive or dormant account. An account will consider as inactive if the user doesn't login to his account and place bets for more than 12 months, which is enough time before considering an account as inactive. A gambler doesn't keep his money on a casino for such long time though, and casino team usually notifies the users by sending two to three emails before considering an account as dormant. Which is a good step before starting to charge the fee.
