Facebook users will soon be able to block adverts in their news feed, starting with ads related to alcohol and parenting. The social network's 1.8 billion users have already been able to select topics they're interested in seeing targeted ads for, like wine or skiing, but this is the first time Facebook has let people proactively block certain kinds of ads from being shown. A Facebook spokesperson commented, “This is an early test that will allow people to hide ad topics they prefer not to see… We are starting with alcohol and parenting since those were the two most common topics that came up in our research." Alcoholism charities have complained about the volume of alcohol advertising on social media, claiming that it increases rates of problem drinking and can cause recovering alcoholics to relapse. The new blocking tool is part of a redesigned ad preferences menu that Facebook announced in September.
