What is CAPTCHA? Why do we need it?
Spam generated by Internet robots is a problem that every website owner will face. You will need to use the powerful CAPTCHA code, regardless of whether you have a blog to share your thoughts, an online store, or a website to showcase your company. To make the most of its benefits, you need to first understand what it does.
CAPTCHA is an automated way to determine if a visitor to a website is human. Named after the phrase “Completely Automated Public Turing Test to Tell Computers and Humans Apart”, CAPTCHA is an automated method of determining if a website visitor is human or not. CAPTCHA is a term that comes from English and means capture.
Any visitor can add or modify any entry on the site. You will need to fill in the field for the word or expression you want. There is a dial beside it that allows you to upload an image. These words and expressions can be written in special fonts, with deformed characters, or colored. This makes the process a bit more complicated. This allows you to distinguish robots that post links or messages for advertising from real users. It was first used in 1997 by AltaVista search engines, which were very popular in 2000. However, CAPTCHA is still one of the most efficient methods to block spamming and is widely used in the web space.
It can also be easily integrated into your website. WordPress users can search for plugins in the plugins menu, click on the “Add New” button after the keyword Captcha, and then install the plugin that is found. Joomla! It’s almost the same at Joomla! There are many free and easy-to-install plugins available on the Joomla! official site. If you have a website built in html, you can simply search for “Captcha HTML code” to find many useful and inexpensive results. Installing Akismet plugin is another option for WordPress sites. Make sure to check the box “Hold a Comment in the Queue if it contains 2 links or more” box.
CAPTCHA codes can have huge benefits, sometimes even stopping spam completely.
You won’t have to delete hundreds or even thousands of spam messages each day.
Spammers’ links do not pose a threat to the site or the computers of visitors.
Do not post images by robots that contain inappropriate, prohibited, or undesirable content.
Avoid losing money on orders placed by robots and not honored (in the instance of online shops)
Google won’t mark your site as unsafe and block access to it.
It was recently discovered that bots can “cheat” traditional Captca codes, even those with 2-words. A new type of code was thus created. A picture is a fragmented image that can be reassembled into multiple pieces. As a puzzle, the user must reassemble and reassemble the image.
These CATPCHA codes can be used to drive away users who are too familiar with the system and don’t have the time or patience to follow these instructions. However, most users prefer clean blogs/sites that don’t contain spam or commercial links. They also tend to return to them. A website with robot-generated links presents security risks for both the owner and the user.
