Google announced it will be adding new features to Chrome 71, starting in December 2018, which will remove ads from sites with persistent abusive experiences.
Site owners are free to use the Abusive Experiences Report in the Google Search Console to see if their sites contains any of these abusive experiences that need to be corrected or removed and will have a 30-day window to fix issues flagged by the report before Chrome removes the ads, according to a Nov. 5 blog post.
Google also noted that more than half of the abusive experiences flagged weren’t blocked by its current set of protections and that nearly all of them involve harmful or misleading ads disguised as system warnings or “close” buttons that do not actually close the ad. Many of these tactics can be used to carry out phishing attacks.
