I’ve quoted the most important part. It is a majority rules system, they don’t need a reason, nor do they have to share it with you. This is not harassment. There are no rules broken.
This is a blue quote about the vote to kick system. Yeah, healers have every right to join islands, just as the rest of the party have every right to kick healers. Like I’ve said, not the nicest move, but perfectly within reason AND allowed by the rules.
