First implementation of CAPTCHA circa 1997

Thanks! I hate it.
Ironically, there are people here bragging about popular scraping software they wrote back in the day
Though not every use of CAPTCHA intends to prevent or limit scraping -- some sites let you read everything with no CAPTCHA, but apply one if you want to write something (or take an action that affects the outside world somehow).
