Messages on MUME boards (both mortal and immortal) are now moderated by a
slashdot-style system (see http://slashdot.org/faq/com-mod.shtml#cm600).
In short, any message on a board now gets a moderated score from -1 to 5, which
depends on the message's content, on the poster's karma (his posting history),
and on the score assigned by the moderators. Messages with score -1 will be
invisible to anyone but the moderators. Some messages will also get a text
rating (for example, Informative, Funny, Troll).
We are planning to copy slashdot's policy of banning abusers. As on slashdot,
if a single user is moderated down more than once in a short time frame, he
may get banned from posting for a few days.
