If influencers are paid, they must disclose it

My son loves to watch expert gamers playing video games on YouTube. Some of these online gamers have millions of followers who, like my son, watch them for hours, know all about them, and want to be just like them. They’re true online celebrities, influencers. I will never understand the fascination with watching others play a video game for hours, but I do understand that if online gamers are being paid to endorse a product in their videos or social media posts, they have to disclose that to their followers. It’s fair and it’s the law.
