Question about compliance of LEGO videos on Youtube and the new COPPA rules
For the time being, it would be smart practice to mark any videos related to LEGO as "for kids," even if that is not your target audience. At the current moment, we know very little about what quantifies as "for kids," but "toys that appeal to children" most definitely includes LEGO. I suspect that we will learn more in the coming months as literally millions of YouTubers try to figure out what their content should be categorized under. At the moment, the risk is simply not worth it. Video deletion, Channel termination, and being fined large amounts of money are all possible if I read everything correctly. With that all said, I am not a lawyer, so I highly recommend you go ask the folks over at the Law Stack Exchange.
