captchas are so stupid if you dont know what a captcha is its a image of 2 wierd distorted words that are really annoying most of the time they have them for signing up for something or if you sign in on another phone or computer. the reason why they are annoying is because they are so hard to understand i looks like l m may look like n and and v's look like u it took me about 10 minutes to create a youtube account 5 for the user names and 5 for the captcha some may look easy but most of them are hard the reason for a captcha is to make sure your not a robot. a robot could not read the letters because of the distrortion text but i could see why they would have it for putting alot of comments rapidly. its because they dont want spams i think? idk but i hate captchas and i will always hate them
The only good thing to come from captchas are the threads on 4chan where people try to draw them in MS Paint.
It is a video of one of the creators of captcha talking at TED. It is about half talking about captcha and half talking about a child project called "duolingo"
