The sender controls the content of the membership event, since the content contains profile data (display names, avatar urls) a sender might incorrectly change the profile of another member inside the room. This is allowed in the case where the sender is kicking or inviting the member, this it will self heal once the member re-joins. Still, to mitigate this a bit we're storing the profile data when we know that the member sent out the content on their own.
