You have a rule for multi-accounting but it is unclear on how you detect them and your definition on multi-accounts. Do you consider accounts with same IP address in a household is multi-accounts? I know many gambling sites have clear rules on multi-accounting.
When it comes to multi-accounting then this would vary on each site because basing off on experience with most one game dedicated site like dice where every users had the
chance or freely create accounts as much as they want as for others do limit out only single account for each ip. Just like on what happened on luckybit
where i do make some new account and when tending to make out some cashouts, it was put on hold due to that multi-accounting reason.
Detecting multiple accounts in one IP shouldnt really be a problem.
