That's where the Google disavow links tool comes in: https://www.google.com/webmasters/tools/disavow-links-main?p...
A model is only as good as the information in it. In this case providing details of these spammy links helps you, and every other site targeted through the same sites/networks/fingerprints.
Consider it a reverse no-follow mechanism.
In such scenario, how does Google determines if I created the links? Does Google have precognitive abilities or it can spy on my communication channels (Gmail, Google Voice, Hangouts etc.) to figure out if I am innocent?
