Belgian police have warned citizens not to use Facebook’s new Reactions, to protect their privacy.
In February, the site launched six new ways of reacting to a post, alongside the Like button. They were intended partly as a way of answering calls for a “Dislike” button – allowing people to share their feelings about posts without appearing to endorse what had been said.
But the Belgian police now says that the site is using them as a way of collecting information about people and deciding how best to advertise to them. As such, it has warned people that they should avoid using the buttons if they want to preserve their privacy.
“The icons help not only express your feelings, they also help Facebook assess the effectiveness of the ads on your profile,” a post on Belgian’s official police website reads.
The site is able to use the tool to tell when people are likely to be in a good mood and then use that to decide when is the best time to show them ads, the Belgian police has claimed.
How to use Facebook Reactions
“By limiting the number of icons to six, Facebook is counting on you to express your thoughts more easily so that the algorithms that run in the background are more effective,” the post continues. “By mouse clicks you can let them know what makes you happy.
“So that will help Facebook find the perfect location, on your profile, allowing it to display content that will arouse your curiosity but also to choose the time you present it. If it appears that you are in a good mood, it can deduce that you are more receptive and able to sell spaces explaining advertisers that they will have more chance to see you react.”
People have pointed out that Facebook’s Reactions tool is helpful to advertisers since it was released. Though the site said as it was launched that it was a way of allowing people to react in more complex ways, it also provides valuable data to Facebook about how things make people feel, as well as encouraging them to interact with posts amid worries that people are becoming less and less personal on the site.
Soon after the feature was released, Facebook also confirmed that reacting angrily to a post would be treated as any other kind of engagement with it. Since Facebook treats engaging with a post as an indication that users want to see more things like it, that means that reacting angrily could lead to seeing similar posts and could be sold to advertisers, too.
