Fetchers visit websites on-demand. They're normally dispatched by apps to present metadata about a link (e.g. the title and thumbnail image) to a user.

Should I Block Google Publisher Center?
Probably not. If you block a fetcher, it won't be able to fetch the metadata it needs to display a link preview. Fewer people will click on the link to your website without this.
How Do I Block Google Publisher Center?
You can block Google Publisher Center or limit its access by setting user agent token rules in your website's robots.txt. Set up Dark Visitors agent analytics to check whether it's actually following them.
