Netflix employs sophisticated AI to detect automated login attempts. Using these tools often results in the immediate flagging and banning of the IP addresses involved. Furthermore, if you successfully "check" an account and log in, the original owner is often notified of a "new login," leading to an immediate password reset and potential investigation. Why GitHub Hosts These Repositories
If a checker tool validates an account and a user tries to access it from a drastically different geographic location than the owner, Netflix often triggers a password reset or a verification prompt, rendering the stolen account useless. netflix account checker github link
