Welcome to the Q&A Forum

Hey there! Sam from Moz's Help Team here! So it looks like there are a couple of problems here - one is that Javascript is used on the page, and if the link follows the Javascript (which we aren't compatible with), this might be tripping us up. That said, it's more likely the formatting of the link that is preventing us from reading it accurately: http://www.screencast.com/t/6qP2w8WDoWY - it looks to be more like some kind of email redirect rather than a typical link, so in this case, it looks like an issue primarily with the formatting of the link in general that's preventing us from picking it up as a follow/no follow. I hope this helps - let us know if we can help with anything else!

Thanks, Guys!  I really appreciate your insight here. It's very helpful.

"Bing had indicated that disavowing was not as relevant as getting the links removed" If you think the links are causing your issues and request them to to disavowed, they will be. It's very hard to give any advice without viewing the URL. There could be any number of factors affecting the site such as thin content, poor backend SEO keyword choices, poorly written descriptions, etc etc. Could you please provide the URL? If it's a privacy issue with the company or client, please send me a PM with the URL for additional advice.
