San Diego County's new Consumer Fairness and Public Protection Unit has filed its first three lawsuits, targeting AppLovin, Roblox and Polymaker, according to Patch and City News Service. County leaders said the cases focus on children's online safety, consumer privacy and 3D-printed ghost guns.

The AppLovin lawsuit alleges the digital advertising platform served inappropriate ads inside mobile games used by children and collected sensitive device information even when parents used controls meant to protect children. The county is seeking injunctive relief, restitution and civil penalties under California's False Advertising Law and Unfair Competition Law.

The Roblox lawsuit alleges the company marketed its platform as safe for children while failing to put enough protections in place to prevent adults from contacting young users. The county said that case also seeks injunctive relief under California consumer-protection laws.

The Polymaker lawsuit alleges the 3D-printing materials company advertised products for creating unserialized 3D-printed firearms, which the county said are illegal in California and San Diego County. The county is asking the court to stop the alleged practices, impose civil penalties and require proceeds tied to unlawful conduct to be surrendered.

For Santee families, the cases are worth watching because the county's new unit is pursuing consumer-protection claims involving children's safety, privacy and products. The cases were filed in San Diego Superior Court, and the county is seeking the remedies described above. This article is based on Patch and City News Service's Oct. 5 report on San Diego County's first lawsuits from the new consumer protection unit.
