Why would Google, via the disavow tool, essentially provide site owners with a "get out of jail free card" for their previous sins regarding unnatural back-links?
Personally I can't think of any good reason why Google would allow a site to disown the "bad" back-links. Particularly given how hard Google has worked the past 10 years to try and identify bad back-links and devalue sites sites who abused loopholes in their algorithm.
I DO however think that the disavow tool is a brilliant tool to get site owners, en masse, to self report all their back-link sins. What better way to validate their own algorithmic "bad-link" detection methods than to compare it to what site owners self-report as bad links? As long as site owners believe the tool is legit, Google gets a ton of valuable data.
But back to the original question I asked, how is Google making their results better by letting site owners disavow bad links?
