It doesn't say a new group, a bigger group, or different group than the 4 people who were mentioned, so it's not clear who they're referring to. They do say, however, that that group was already unbanned by the time of the update, so where are they? Why don't we see anyone saying they got unbanned? Clearly it wasn't a big group if it was more than those 4 people or else somebody would have spoken up.
