During the SMX West conference, in the “Google Manual Actions” panel, Google’s Juan Felipe Rincon said that the company is taking action on 65 percent of the 35,000 user-generated spam reports submitted to Google every month.
Juan said that of those 35,000 submissions, 65 percent of them are spam, so action is taken manually on these reports.
Google prioritizes the spam reports based on how significant they can be on Google searchers. There are some users who are are good at spam reporting, and in this situation, Google may prioritize the spam reports that are submitted by users who are submitting good spam reports.
