Currently any URL I submit for the project (Clicking “I’ve completed this challenge”) is accepted with a green check mark. I’m new to the site, but I’m assuming the submitted URL needs to be checked that it implements the user stories.
FCC allows campers alot of freedom when it comes to their projects, it is designed in such a manner that these projects only need a valid url to “pass”.
If someone passes the challenge and earn the certificate that way, they are cheating themselves.
Hope this answers your question.
