This isn't a Mr Beast problem, it's a industry problem:

> Frontiers: How Much Influencer Marketing Is Undisclosed? Evidence from Twitter

> We study the disclosure of influencer posts on Twitter across a large set of brands based on a unique data set of over 100 million posts and a novel classification method to detect undisclosed sponsorship. Using our preferred empirical specification, we find that 96% of sponsored posts are not disclosed. This result is robust to a series of specification tests, and even a lower-bound classification still yields an undisclosed share of 82%. Despite stronger enforcement of disclosure regulations, the share of undisclosed posts decreases only slightly over time. *Compared with disclosed posts, undisclosed posts tend to be associated with young brands with a large Twitter following. Using an online survey, we find that many consumers are not able to identify sponsored content without disclosure.* Our findings highlight a potential need for further regulatory scrutiny and suggest that researchers studying influencers must account for undisclosed sponsored content.

Now, one could argue that Mr Beast has the means to properly disclose these issues.
