I tried putting in my github account on the home page just to see what would happen.

I didn't create an account or sign in, but it created a public profile on your domain using my name without my consent.

Is there any way to remove that?

In that case, it's just reading the public data from GitHub on demand, there is no account, nothing stored.

Ah ok, it looked like maybe it was created and cached and then publicly accessible at backyourstack.com/foo since that's the URL it forwards you to.

You might want to anonymize that URL for accounts who don't sign up just for clarity.
