This extension collects political ads on facebook.
The Political Ad Collector is a crowdsourcing tool, built by the nonprofit investigative journalism newsroom ProPublica, that will gather political ads from user's Facebook News Feeds.
When users log into Facebook, the tool will collect the ads displayed on the user's news feed and guess which ones are political. The tool will also show users political ads that others are seeing, but that weren’t targeted at them.
The tool does not collect any personally identifiable information, and will not learn which ads are shown to which user. The political ads that are collected will be contributed to a public database.
This extension is in partnership with the following organizations: Openpolis (Italy), Republik (Switzerland), The Guardian Australia, Der Spiegel (Germany), Süddeutsche Zeitung (Germany), Tagesschau (Germany), Dutch Public Broadcasting (Netherlands), and the Information (Denmark).
