How to identify a bot on a website?

Question

JavaScript

How to identify a bot that clicked on an ad and went to my site?
Suppose it executes JS, well, it supports cookies by itself and changes ip. Moves the mouse and clicks somewhere on the page randomly... or not randomly....

Answer 1

I myself often wrote bots on AutoIt and that's what I was afraid of -

• What will they talk to the bot
  
• That the admin will notice that there is always exactly the same interval between events
  
• That the admin will notice that when you click on the button, the cursor always hits exactly the same pixel
  
• That the user interface will change and the bot will start doing indecent things (and usually there are enough changes that are not visible to the eye, for example, change the button id or change the color from #aaaaaa to #aaaaab)
  
• What admins will notice is that my online tends to be 24h a day
  
• That admins will notice that even if I don’t have 24 hours online, it doesn’t coincide with the usual user activity time for my time zone (I didn’t install the bot while I was sitting at the computer, so it usually worked at night)
  
• That the admins will throw some kind of joke (for example, a message will pop up in the middle of the screen) and the bot will become blunt and burn out (for example, it will start to stupidly poke in the same place)
  

Answer 2

make the buttons the wrong size and click in the visible part is a person, if the bot, then he will click "past" :)))
ps If it was simple, then there were much fewer bots =)
If you want to protect yourself from a specific bot, then this task solvable, and so .. 50/50
