Seems like this made the rounds on the blog circuit a few weeks ago: "You're in a desert, walking along in the sand when all of a sudden you look down and see a tortoise. You reach down and you flip the tortoise over on its back. The tortoise lays on its back, its belly baking in the hot sun, beating its legs trying to turn itself over but it can't. Not without your help. Do you flip it back over? Type your answer below." IIRC there was an abbreviated test that simply asked: "What color is an orange?" On my own blog I've found it pretty effective to simply block any comments with more than a certain number of URLs in the body. Also, the Akismet spam filter on Wordpress has been remarkably efficient. It's filtered out hundreds of spam comments with no false positives and only one false negative since I started using it. I've never looked in to how it works but it doesn't require anyone to "prove" they're human. // jeff . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
