There's a very clear hide link to click, there's no need to open Dev tools like the other comments are suggesting.

You may be the Chosen One. I don't see a hide link on the overlay that obscures comments.

I see no such link to hide it. The only links are "Sign Up With Facebook" and "Sign Up With Google."

[marssaxman]

I refuse to click such links on principle; if they want to hide their content, I will direct my eyeballs elsewhere.

Checked in IE 11, Chrome, and FF, and I don't see any hide link.
