If you use Google search (and really, who doesn’t?), you’ve probably noticed the big warnings that appear when you try to click on some search results. That’s Google Safe Browsing (GSB), protecting you from a malicious web site.
GSB flags sites that fail to comply with Google’s Malware, Unwanted Software, Phishing, and Social Engineering Policies.
To get rid of the warning, the owner of a site flagged by GSB must remove objectionable content and resubmit the site for verification in Google Search Console. Until recently, this process could be repeated indefinitely.
To counter repeat offenders, Google has changed the way GSB works. If a web site repeatedly fails to comply with Google’s Safe Browsing policies, it will be flagged as such, and the warning users see will appear for at least 30 days.
In the announcement for this change, Google points out that the new repeat offender policy will not apply to sites that have been hacked (i.e. changed without the owner’s permission).
