Account can't be verified for initial sign up

I’m a newbie trying to set up an account for a class I’m taking. I tried to sign up yesterday using my email but got an error that my account “has been flagged by our automatic fraud protection system.” Clicking the link in the email didn’t help. I then tried to sign up using my GitHub account but that didn’t work either. What can I do to set up an account?

@jraby when you say clicking the link in the email didn’t work, could you elaborate on what that means? Were you able to complete the identity verification steps?
