As someone who worked for a major sports betting company, these are the things we built but only used if required by the country/state/tribe/whatever: * Deposit limits, per day/week/etc to limit the damage someone could do and also to limit money laundering. This could be self imposed or regulator imposed. * Withdrawal limits. This was mostly to limit money laundering. * Wager limits, per event/day/etc * Self exclusion for a certain time period or forever. This kept people from using our stuff to make bets based on our best efforts to identify them. Sometimes we had a government ID, sometimes we didn't. * Other exclusions, i.e. blacklisting for things like not paying child support. * Geofencing to prevent people from using our app outside of the legal jurisdictions. Also, geofencing to only allow people to register for our apps in certain locations, such as a casino. That could easily be extended to prevent people from using the apps outside of a casino, but I don't think that was required anywhere. These things are technically possible and would greatly help if required globally, short of an outright ban.
