The only thing you can do at this point is to petition the D1 users to exclude OG.
Two DT1 exclusions won't kick out another DT1 member. What would that accomplish?
Where did you get the 2 exclusions from? You would have to get more than 2.
I figured that since: 1 DT1 inclusion is *disabled* by 2 DT1 exclusions (which is what temporarily happened to me) once, that the same goes for higher up.
Good point, maybe we need Cyrus or Theymos to clarify this.
