A father says his 9-year-old son spent $118,000 on YouTube ad campaigns for his Minecraft and Roblox gameplay videos over about three weeks, all charged to a company credit card the father had saved to his own Google account, which his son also used. The father, who identifies himself only as Dave, described the incident in a video titled “Message from Dad…Mighty Mike Plays is Over.” posted to the boy’s channel on Sept. 15. Dave said he was called into a meeting with his manager, corporate staff, and finance and shown the advertising charges.
