MGM is something you have to prove, for MGM you need to prove yourself a good GM 3rd highest rank in SCB. MGM stands for Master Global Moderator which means you get the something's as GM's but along with double the features, such as when you have the Minecade mod you can turn on a swearing filter which means when someone swears it gives them a warning and will kick them which also go's with spammers you can also go into creative mode and tp to players and there's a MGM table in the SCB lobby, plus MGM's are really hard to find and beat in Walls or SCB. And extremely respected by the community.
