Copyrighted Haiku Delivers Spam Through Filters

An anonymous reader writes "Remember that antispam company that includes a copyrighted haiku (which I can't quote here due to copyright reasons...) in emails vouching for their nonspaminess and thus bypassing spamfilters? The idea is that a spammer using said haiku to get through spamfilters can be prosecuted under the more stringent copyright laws instead of the weaker antispam ones. Well it seems said haiku has lately been figuring in a large spam run trying to pitch the usual medical remedies for various unfortunate ailments. What do you think? Is it time to start filtering for haikus or will Habeas succeed in thwarting the spam attack?" We mentioned this brilliant anti-spam scheme last April.
