Per the previous post.
The owner of this website (www.weaselzippers.us) does not allow hotlinking to that resource (/wp-content/uploads/2015/05/Screen-Shot-2015-05-18-at-8.29.43-PM.png).
I could have downloaded the image and never mention Weasel Zippers. It isn't even your Tweet that you are blocking access to.
My apologies for sending traffic to your site. It won't happen again.
