Yeah, I was out on the road or I'd have checked it sooner. We need you to come back as a moderator, NJ.

The certificate error must have been from the site in the hidden link. I see a red x in a little window like you see when an image is missing, but jsanders didn't see that. Do you see it? Or if you hover your mouse over the lower left porting of his post area, do you get an indication of a live link?
This is a relatively new spammer trick. Some have used emoticons as links, only they don't work usually and I can see the red x then also. If you hit the quote or edit buttons on their posts, you can see the code for the link.
Edit.. this is what I see... in screenshot.
