Houston we have a problem. If you never heard of 80legs, you are lucky. One of my main sites was shut down because of this pesky little bot that crawls your site and mines information known only to the user. The bot originates from Houston and has been causing havoc on servers globally. My hosting company shutdown my site because of this pest. It’s very easy to get rid of this creepy crawler bot. Add the following lines to your robot.txt and you should be fine.
