Are you talking about the group log since that the only way to see switch of your group members have been plundered? If so then in my opinion, its a good way to track outside from your group who is a plunderer so your group members can figure out his plunder habits and avoid him and also track if a group mate gets plundered by the same person.

I highly doubt Oasis will ever remove the group log or even remove the notification that lets the group know which member got plundered. If your group members are emotionally affected by this then they need to rethink if they can get emotionally stable to convoy. Keep in mind, whether or not you get plundered, you still get coupons if you attempt a ss mission.
