I wouldn't use this type of tool until I've confirmed a penalty. I have no interest in policing other sites content for anything but copyright violations. Who am I to tell another webmaster who they can and cannot link to. This tool is an extension of that mentality in that it still requires policing but helps Google by using my time and resources instead of theirs.
I am curious however, can I disavow my own "read more", affiliate and nofollow links? It will be interesting to see. I would be surprised if they allowed the tool to be used in this manner since they despise link sculpting but we'll see.
Bottom line - if Google doesn't tell us specifically which links are sour it's just a guess on our part. I'd prefer they simply disavow sour links on their own, ya know? It still rubs me the wrong way that things on sites I do not own can impact my rankings.
