question

I have experimented a bit with user bans to better understand how they work, and I found that when a user is banned not only via their PlayFabId but also by a given IP address, then this will also block any other user that would share that same IP.

This is also noted in the API documentation for the BanUsers API call:

https://docs.microsoft.com/en-us/rest/api/playfab/server/account-management/banusers?view=playfab-rest#banrequest

I then tried to replicate the same using the MACAddress field of the ban request, but so far this one does not seem to do anything at all ?

Could you please elaborate what the MACAddress field is used for? In the PlayFab players dashboard it also nowhere shows the players' MAC address ?

PS: I am also asking this because I am evaluating how to use PlayFab in conformance with the GDPR and so I am wondering if (aside from the user ban table) are MAC addresses stored anywhere in a PlayFab title's database?

Thanks
