>I did try writing to yahoo, but just got a form letter back.

you have to get extremely lucky to reach an intelligent lifeform at Yahoo!® -- the bots are in control over there. otho, their profits are going through the roof, now that online adverts are in again.

I've had several run-ins with spamcop sending out the daily wwftd. one in particular I remember fondly; it included some lines from the amphigory: the owl and the pussycat.

here's another ludicrous situation: the AoL (ha!) spam filters are having issues with Yahoo! mail, because yahoo turns all mail into virtual spam!
