The state of an
online forum thread which has been locked by an administratior or moderator on the basis that the subject matter is too trivial to warrant further discussion. Typically a concluding post is
made by the moderator to the effect that the discussion to date has
made a "mountain out of a molehill" before the thread is locked for further discussion. Threads tending towards criticism of the moderator's organisation
may sometimes be pre-emptively molehilled to avoid further negativity to propagate.
Poster1: Hey, respond to my post about Germaine
Greer's new
book!
Poster2: I can't. It's been molehilled.
Moderator: This is going nowhere. Molehilled.
