Do We Need to Do That?

Brody Clark: If Google hasn't identified that link, it's again by definition probably going to be giving you some benefit from it. You could actually potentially harm your rankings if you chucked a load of links into disavow. I've encountered that before where disavowing what seemed to be spammy links or perhaps have been mislabeled can actually negatively affect you there. The risk is higher than the reward for me, in my opinion.
