Facebook Blocks Ad Blockers, but It Strives to Make Ads More Relevant - The New York Times

"To shut down the blockers, Facebook is taking aim at the signifiers in digital ads that blockers use to detect whether something is an ad. Facebook’s desktop sitewide changes will then make ad content indistinguishable from non-advertising content. For blockers to get around these changes, Facebook said they would have to begin analyzing the content of the ads themselves, a costly and laborious process.

Still, Facebook will continue to let people have some control over the ads they do and do not see. On Tuesday, the company also introduced an overhauled version of its ad preferences tool, which lets people opt out of seeing certain types of ads on the site. That will help Facebook serve more relevant ads, rather than bombard people with ads they do not want.

“We want people to help us do a better job with ads, rather than to fundamentally alter the way the service is rendered,” Mr. Bosworth said."
