RTÉ broadcaster Miriam O'Callaghan has been granted an order by the High Court requiring Facebook to give her information to help identify those responsible for alleged defamatory adverts.
Facebook did not consent or object to the orders granted by the court.
The orders require Facebook to give Ms O'Callaghan's lawyers basic subscriber information, payment method details and business manager account information about those behind the adverts, if such information exists.
Ms O'Callaghan intends to seek damages over the adverts containing her name and image on Facebook and Instagram in May 2018.
She alleges the ads are false and malicious and wants to bring proceedings against Facebook, who also owns Instagram, and those responsible for the adverts.
Her lawyers sought today's orders in an effort to get Facebook Ireland to provide any information it has about who paid for the adverts.
The court was told today "progress had been made" and Ms O'Callaghan's senior counsel, Paul O'Higgins, handed an order into the court.
Mr O'Higgins said that ordinarily Facebook notify customers before providing details of their accounts but he wanted that bypassed.
He said they did not want the account holders to be informed in advance, although he said the account details "may be phoney anyway".
Ms Justice Leonie Reynolds agreed to make the order. The matter will back before the court later this month.
Ms O'Callaghan's lawyers told the court on a previous occasion that Ms O'Callaghan was most distressed at being associated against her will with what was described as a "scam product".
The court was told the adverts contained misleading and defamatory headlines, wrongly suggesting Ms O'Callaghan had left her job with RTÉ’s Prime Time to promote skin care products.
She says she had nothing to do with the adverts.
Ms O'Callaghan said they were exploiting the trust placed in her by the Irish public and had damaged her good name and reputation.
The ads are known as "targeted advertisements". Those who click on them are offered products falsely stated to be endorsed by Ms O'Callaghan.
She also claimed users who availed of an offer of a free trial, had money debited from their bank accounts, which they did not authorise.
