Dublin (CNN)Attempts by Facebook and Google to tackle "dark ads" and foreign interference in the run-up to Ireland's referendum on abortion haven't been entirely successful, data from a transparency group seen by CNN has shown.
The Transparent Referendum Initiative (TRI), a volunteer organization set up to monitor social-media posts about the referendum has collected ads from 180 Facebook groups targeting Irish voters.
