Nothing is as tricky as telling a lowercase \u201cl\u201d apart from an uppercase \u201ci\u201d or an uppercase \u201co\u201d from its smaller counterpart. There are plenty of crazy examples, but mostly just frustrations.<\/p>\n<p>Those strange codes are called CAPTCHA codes. CAPTCHA stands for<em>\u201cCompletely Automated Public Turing test to tell Computers and Humans Apart.\u201d<\/em> In short, it\u2019s a test to distinguish humans from computers.<\/p>\n<h2><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-7920\" src=\"https:\/\/are-agency.be\/wp-content\/uploads\/2019\/05\/Are-Agency-CAPTCHA.jpg\" alt=\"\" width=\"300\" height=\"57\"><\/h2>\n<h2>Why do websites use CAPTCHA?<\/h2>\n<p>The reason websites use CAPTCHA codes in their registration process is to combat spam. Those strange little letters are a way to verify that the person trying to register is actually a human being and not a computer program trying to access the website in order to flood it with spam.<\/p>\n<p>Yes, it\u2019s frustrating to have to keep entering those annoying codes from the images, but it\u2019s worth it in the long run. Anyone who\u2019s ever set up a blog or website knows what spam looks like up close, even if your website or blog barely generates any traffic. Smaller websites or blogs are actually easier to find because they\u2019re usually not as well secured.<\/p>\n<h2>CAPTCHA protects websites.<\/h2>\n<p>If a website or blog owner didn&#8217;t use security measures like CAPTCHA, they would receive dozens of spam registrations and messages every day. And we&#8217;re only talking about smaller websites or blogs here\u2014just imagine the amount of spam larger ones would receive.<\/p>\n<p>So the next time you come across one of those fun images with weird little letters and get frustrated because you can&#8217;t tell the Q from the O, don&#8217;t blame the website this time\u2014blame all the spammers instead. Spammers are the reason these codes exist!<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Grrrrr, is that an \u201ci\u201d or an \u201cl\u201d?
