I think those guilds that made a "No Bot" pledge probably didn't anticipate all the possible combinations and changes. Also some people don't think that a battle helper is a bot, since the human player can see the recommendation, and modify based on their experience. I suppose that's what makes it complicated. So for me, I like to call it "Bot Brains".
You should know that many of these guild leaders are very interested in the activities of their members, and a number have asked many follow up questions in private. I truly believe that most of these guild leaders want to keep their members committed. But another problem is that many of these kinds of tools are very hard to detect.
