CAPTCHA are the same anthropological codes that you have to do to enter different sites. On this site, all you have to do is fill in the captchas they give you. There are two types of captchas on this site. Either they are in written form, in which case you must enter the code you see in the image in front of you correctly in the corresponding box, or they are in the form of images and you must enter the appropriate images that have been asked of you. Choose.
