My apologies if it already does this, but could part of the "So and so has been removed from the guild" message include who did the booting? I know some guilds have been having problems with griefers and it's hard to track down who's causing the problem if they have more than a couple officers. It might also dissuade people from griefing if they know it's no longer an anonymous act. It won't stop the determined, but at least it would be easier to track them down, remove them from the game and keep them from doing it to another guild.
