Heh. I've had my WordPress SLOweather blog up for over a year now. I get a hundred or more spam "comments" a day. I either need to disable comments entirely, or add one of those graphic thingys to validate the perps.
I put up a custom asp based contact page on SLOweather to keep the spam harvesters at bay. Now it's getting spammed. Not a lot yet, maybe one or two a week. Some of them have figured out the sending part, but the message comes through blank.
