Filtering
NTK has some hilarious coverage of Yahoo keyword filters, which lead, NTK notes, to "medieval" appearing as "medireview".
I observed that the same substitution ("review" for "eval") leads to reviewuate, reviewuation, retrireview, prreviewent, and even primreview. ("Medieval" and "primeval" both incorporate the Latin aevus, which means "age" or "time"; "primeval" is pertaining to the first age and "medieval" pertains to the middle age.)
Yahoo also replaced "expression" by "statement", leading to oddities like Statementism (the artistic movement, doncha know) and the political virtue of freedom of statement.
(This subsequently appeared on slashdot.)
