   Those, even if only a checkbox you click, are looking for behaviors   
   (events) exhibited by humans visiting a web site versus bots or web   
   crawlers trying to harvest content, or zombied hosts attempting DDOS   
   (Distributed Denial of Service) attacks.  The site assaults their good   
   visitors with anti-bot/DDOS/webcrawl filtering.   
      
   Their CAPTCHA could be a simple checkbox you click, and they'll notice   
   it takes you time to move your mouse to click on it versus a bot that   
   instantly clicks on the checkbox.  Could be "match the tiles" on some   
   common theme, like all tiles with bicycles, or you drag a tile to fill   
   in a jigsaw picture, or you solve a math formula.  The site assaults you   
   with interferrence trying to protect themself from bots, web crawlers,   
   and DDOS (Distributed Denial of Service) attacks.  They're hoping to   
   protect their site to keep it responsive to real visitors by   
   interferring with accessing the site by bots, but it is interferrence to   
   their good visitors, too.  In effect, it is a weak form of requiring all   
   visitors to login before the site delivers its content.
