Ne Pornbots Pas
After returning from Tennessee, I was not much amused to find that the pornbots had found my site and filled my comments with porn spam. Hundreds of 'em. Luckily it's pretty easy to scrub the crap from the database and turn off anonymous posting to the blog posts. Since the bots can't register, they can no longer post.
Great no more spam. However - I'm also aware that most of you viewers are too busy to be bothered with registration or logging in or whatever (laziness or fear.) So now you won't post either when tempted to leave a brief note. So to solve all of this, you'll now notice that a security graphic test must be passed in order to post comments. The bots can't "see" so they fail the test and can't post. You anonymous users however, if not blind can see the numbers to type in and leave as many un-authored comments as you wish.
Thank you very much. More clever coding brought to you by the Goobermaster.
