Facebook is still tangling with the problems that came to light in August when the company revealed it had been overestimating time consumers spent viewing video ads on its sites.

Three advertisers have filed what they hope will turn into a class action lawsuit over the practice.

“As a result of Facebook’s ‘fraudulent’ conduct, plaintiffs and members of the class expended money on advertising that they would not otherwise have spent based on a false belief that the advertisements were more successful than they actually were,” a suit filed in a San Francisco federal court claims.

The suit, brought by Tom Letizia, Mark Fierro and Greg Agustin Jr. — a trio of public relations and marketing professionals — seeks unspecified actual and punitive damages.

Facebook admitted that, because of a miscalculation in the way it determined the video-ad viewership, it artificially inflated the time spent watching videos by 60 percent to 80 percent from 2014 to 2016.

A Facebook spokesperson said the suit “is without merit.”
