What's a bot?
It's a cyber-crawler computer program that wanders websites and looks for keywords, Billy. So when you Google, or Yahoo, etc., you can find this site by searching "Book & Forum" or some other variation. Sometimes you can see them pop up in the middle of the night. Some metacrawler companies have a sense of humor and make them LOOK like spiders. Some spammers have cyber-bots that can find a log-in page to a site like this by looking for keywords. Then the bot has coded instructions to add the proper data to the proper boxes so that the hacker can spam the site. However, a bot CANNOT read the bent and twisted image letters to recreate them in the verification box, because it's an image rather than text (and they're bent and twisted).
evil penguin could be trained to do that
Ah, you would be wrong there, Billy. EVIL penguins are too smart to be trained. They think independently. It's why SillyWabbit fears them...
