Hey Jason - Author of the post here. Thanks for the catch, updating the post now. If you drop me an email or twitter DM (details in my profile) and I'd love to send you a t-shirt as thanks for catching this.
Why do you put CF tracking ref= turds in the 3rd party links in the article? Is that really necessary?
You're right, those aren't necessary. That was a setting on our blog CMS that was enabled with a recent upgrade. This is now disabled (it may take a bit for cache to clear and you see these disappears). Thank you for calling this out!
What, no free t-shirt? ;-) Just kidding, thanks for fixing this so quickly.
