Facebook has stopped offering advertisers free ads on its Facebook.com ad site after they violated the company’s ad-tracking rules, according to a post on its blog.
Facebook will continue to provide advertisers with a link to their Facebook ad on other sites, the post said.
“Advertisers are using the ad-targeting tools available to them to target ads to Facebook users, including Facebook ads.
We don’t want that,” Facebook said.
Facebook did not respond to requests for comment.
Facebook started selling ad-blockers in January.
It’s now available on all versions of the site, except for the premium version, which has ads that block ads.
Advertisers can opt out of Facebook’s ad blocker, but it’s not clear how many do.
Facebook has been criticized for the way it handles ad targeting.
The social network has been accused of favoring ads over other sources of traffic, and has been sued for doing so.
Facebook said in a statement it’s working to make its ad-blocking tools more user-friendly.
“We’ve been making some updates to help marketers and advertisers better understand what their ad targeting options are, and what they need to do to get approved,” the company said.
Facebook said it has not been contacted by advertisers who have been blocked by the new system.
“We’ve always worked with advertisers to make sure that we provide them with the best possible experience, and this update is a step in that direction,” the Facebook spokesperson said.
