Google loves when webmasters and SEOs report search/web spam to them. Although 70% of SEOs won't report spam to Google, there is still a huge number of people who would. To make it easier for those spam reporters, Google has created a Chrome Extension named the Google Webspam Report.
I don't know for sure who made the extension at Google, but maybe it was Matt? Maybe?
There is a Google presentation on how it works, which I will embed below. The extension has:
- Adds links to search result and web history pages to report spam quickly.
- Prepopulates the spam report form where possible.
- Select a spam url from your Chrome history.
- Cycle through your recent Google searches to fill fields of the spam report page.
- Options page to enable/disable features individually.
