Parent and consumer advocacy groups claim Facebook allowed children to make expensive in-app purchases on the platform without parental consent in a complaint filed to the Federal Trade Commission on Thursday.

Facebook isn’t the first tech company to be hit with such a complaint; Apple Inc., Google and Amazon.com Inc. all previously faced FTC action following similar allegations. Lawyers and advocacy group leaders said there are ways tech companies can make online gaming safer for children and ensure their platforms comply with relevant data protection laws.
