What is displayed at 'Humans Not Invited' is a blur image at first glance, but according to producer damjanski , a bot with a specific program can determine which is the correct image just by looking at a small pixel on the image It seems to be possible.

According to Motherboard of an overseas media who spoke to damjanski by email, “Images that appear blurred to humans can be seen clearly through the algorithm and can be used as CAPTCHAs. For example, CAPTCHA is a“ square Ewalk. `` Choose '' and tell me that there are blurry Ewalk images on the screen. Because I use a program that changes the image name, it is useless for humans to try to judge from the file name of the image. '' I told you.

The reason why damjanski is improving `` Humans Not Invited '' so that it can not break through to humans is that many Internet users have announced `` Humans Not Invited '' on Hacker News and `` Humans Not Invited '' Because we have created a bot to break through.

According to damjanski, more than 30 bots have surpassed 'Humans Not Invited' so far, and if you clear the certification, you will see 'Welcome! You are not human'.

Although the reporter of Motherboard also tried `` Humans Not Invited '', it seems that he could not break through eventually, but on the overseas bulletin board reddit reported that some people succeeded in breaking through without bots .
