Answer:
   
   It depends on your definition of censorship. The Merriam-Webster
   dictionary (at [5]www.m-w.com) defines censorship as follows:
   
     Main Entry: cen·sor·ship
     Pronunciation: 'sen(t)-s&r-"ship
     Function: noun
     Date: circa 1591
     1 a : the institution, system, or practice of censoring b : the
     actions or practices of censors; especially : censorial control
     exercised repressively
     2 : the office, power, or term of a Roman censor
     3 : exclusion from consciousness by the psychic censor
     
   "Censor" is defined as:
   
     Main Entry: 2censor
     Function: transitive verb
     Inflected Form(s): cen·sored; cen·sor·ing /'sen(t)-s&-ri[ng],
     'sen(t)s-ri[ng]/
     Date: 1882
     : to examine in order to suppress or delete anything considered
     objectionable
     
   Hence, under this broad definition, moderation can be viewed as a form
   of censorship: objectionable material is not permitted in the
   particular venue. However, there are some arguments against calling
   moderation censorship:
     * Censorship usually implies removable of objectionable material by
       the government. When done by a private enterprise, such as the
       editor of a magizine, it is viewed more as editorial control.
     * Although the particular moderated group may be "censored", USENET
       as a whole is not censored, as for each moderated group there is a
       suitable unmoderated forum to which the material can be posted.
       These are listed below:
          + mod: soc.culture.jewish.moderated
            unmod: soc.culture.jewish
          + mod: soc.culture.jewish.parenting
            unmod: soc.culture.jewish or misc.kids
          + mod: soc.culture.jewish.holocaust
            unmod: soc.culture.jewish, alt.revisionism, soc.history
          + mod: rec.food.cuisine.jewish
            unmod: other rec.food newsgroups, soc.culture.jewish
          + mod: rec.humor.jewish
            unmod: alt.humor.jewish
          + mod: soc.geneology.jewish
            unmod: soc.roots, soc.culture.jewish
          + mod: alt.religion.judaism.orthodox
            unmod: soc.culture.jewish
       
   Do people prefer a moderated newsgroup? Some do and some don't. It is
   only recently that moderated spinoffs from soc.culture.jewish have
   developed. This is due to the increased traffic on Usenet, and the
   changing nature of the Usenet audience from the early academic focus.
   
   Many on S.C.J feel that part of its appeal and taam
   (flavor/tang/spice) comes from the freewheeling unmoderated approach
   which brings together posters from all parts of the spectrum. However,
   many have tired from the intrusion into the group by others with
   specific agendas to push that are decidedly non- or anti-Jewish.
