I’m not 100% sure if this is still what they do, but i can say that my brother owned a group on his old account. When his account got terminated it still stayed the owner of the group. So now anything that was owner only permissions cannot be accessed, like the group funds, role manipulation, and ownership transfer. If you want to avoid something like this, then i believe it is possible to just make a dummy roblox account, make the that owner, then make a role right under that, that has all permissions, and put your main account in that role.
