Facebook ad library failed to serve its purpose, say experts

New York: Researchers and experts have slammed Facebook for making its Ad Library — meant to bring a new level of transparency to online ad buys — riddled with errors and technical glitches that make it virtually unusable.
In a statement shared with IANS, US-based non-profit organization said on Saturday that it is disheartening to hear that Facebook’s Ad Library has been hobbled by technical limitations and errors.
“While we commended Facebook in March for establishing the database, we noted back then that the company needed to take additional steps to ensure the Ad Library was both comprehensive and effective”, said Summer Lopez, senior director of Free Expression Programmes.
