Generally as mailing lists approach a certain size/popularity they must be moderated. Even if 99% of the people on the list follow etiquette perfectly, never post off topic, etc, etc that stills leaves %1 who will. If you list has over 1000 people this quickly leads to high degree of noise, which seems to usually follow a self amplifying pattern. As people post more off topic questions and get a response (people trying to be helpful and all) it encourages other to post off topic, as well there are more responses, some of which are not really needed (me too!). Like a lot of security professionals I receieve a lot of email in an average day (100-200), even if I only scan them and do not reply/etc that's still a lot of time. Moderation ensurses (to a much more certain degree) that the emails I receive from this list will be worth reading and useful. As SuSE pointed out this will not mean censorship (and I have yet to see a professional security mailing list where that was ever a complaint, and I'm on over 20 =), it simply means the wheat will be seperated from the chaff so we don't have to.
