I remember seeing user asking for help because they couldn't solve a question. I figured it must have been difficult and they were losing members. Nope, the user just wasn't paying close attention. The question was "What year did the War of 1812 take place?" I implemented this system on a previous incarnation of my site, as soon as I did spambots finally stopped registering. Pesky things.
