I'm not sure what's more distasteful, the idea of someone bashing a new member's taste in books when they first join
I'm guessing that the organizers are considering situations other than discussions where people (especially new members) mention their favorite books, and then someone jumps all over them about their choice. A new member could be sitting their quietly, trying to get comfortable when other participants start trashing the very book that opened his/her eyes to the possibilities and acceptability of TTWD. Quite unknowingly, those people may make the new member uncomfortable, when the goal is to be welcoming. I don't know; I'm just speculating. In my experience, rule-making (good or bad) in any situation is in response to actual problems that have occurred.

What is d/s Munch?
A "munch" is an event where people interested in BDSM get together socially over a meal, generally in a restaurant, without any BDSM-related activities taking place. It's an opportunity to make friends, or just to hang out with friends, perhaps (but not necessarily) talking about BDSM-related topics. It often, but not always, precedes a "play party" in a nearby venue. Therefore it allows a newbie to become comfortable with people who will be attending, and perhaps learn more about how things work.
