I guess we have different ideas regarding the free market, and the meaning of CENSORSHIP. This is a for-profit enterprise and the moderator represents it. S/he makes judgments about what to cut out, and cuts it out. If s/he cuts stuff that too many people think ought to stay, s/he eventually loses business to the point where the site ceases to operate. 98 is free to take a hike and spew his speech elsewhere, and the moderator is free to delete his posts if he stays or ban him entirely.
