Yes - but that doesn't work on Realms and requires the server to trust a 3rd party for the bans list and only works if you use Bukkit. Those problems are solved by Microsoft running the program. But it needs to be optional - ideally opt in. Since Realms is mostly for kids I think it makes sense for this feature to be opt out, or even always on, in Realms.
