I tested this myself and is true, some of the cards that takes you to other subpages are blocked except 1, and the one not blocked has the same structured as the rest of the cards.
We are talking about http://colorsandfonts.com
Has anyone faced this?
Thank you and have a great day

##.sponsor_block
You have the class name `sponsor_block` on some of your cards, so it hides them.
