A bug in coursera registration

This is the first time I use this browser/computer to visit coursera.org.

I clicked "register"(or sign on?), and click "use my facebook account to register".

Then in the next page Safeguarding Your Privacy: "By checking this box, I confirm that I have read and agree to the Terms of Use" I regretted. My facebook is too personal. Maybe I can use my Google account? 

I don't want to continue. So I select the next link "I don’t want to agree. Please delete my account instead." The good news is that there are options for me to select what data to delete, and I can choose all of them:

 

The bad news is: I need input my so call password. I haven't actually created the account, created a password yet. 

So I can't proceed to "delete" my account, which doesn't actually fully created, doesn't exist yet.

Not a big deal. I will just go to the homepage to create a new account, using the Google account I am thinking of.

Dang! When I go to the homepage, it shows up the  Safeguarding Your Privacy: "By checking this box, I confirm that I have read and agree to the Terms of Use" again. And the only options I have are the same: Either agree with the terms, or go to the Deleting Your Account page which I can't proceed without the non-existing password.

I can't get around this. I left this for 48 hours, came back to it, and still got the same pages.

I actually Googled how to delete cookies from a site, and removed 4 cookies of coursera.org. Go to the home page of it and got the same thing.
