    a) Anomy is not an antispam tool.

    b) Lots does, the false positive rate on such a check is so high
    that it's virtually useless for classifying spam.

    This might be useful to help recognize non-spam (to offset false
    positives caused by other heuristics in anti-spam software), but
    that's a slightly different problem... and has nothing to do with
    Anomy.
