What colour is the Universe? It’s beige. (Something to do with the average wavelengths)

The reason captchas don’t work these days is that spammers often “outsource” them to actual people. I watched a video of a talk at Google where they discussed this, among other things. Apparently what happens is the spammer will have a “free” porn site somewhere, but in order to view the images, visitors have to solve captchas… and every time they do, the spammer gets another email address or forum account.

Sadly, the WP-gatekeeper riddle approach is just as vulnerable to this tactic, but it will probably work fine until it becomes popular enough to make it worth it to the spammers to “outsource” the riddle solving too. Welcome to the arms race =)

Little Red xxxxxxx?
a) Hedgehog
b) Rooster
c) Axolotl

Thanks mate, you’ve saved the forum. Email me if you need cash or anything.
