Per Kyunghyang and others, concern is spreading that short videos and recommendation algorithms absorb teens' time and steer them toward increasingly provocative content; the government has reviewed and announced regulatory measures in response.

The 'rabbit hole' refers to how one video leads endlessly to a similar or more provocative next one. Critics say designs that make it hard for users to stop on their own fuel addictive use.

Regulatory directions cited include stronger algorithmic transparency, limits on recommendations and exposure aimed at minors, and mandatory use-time management features—though balancing free expression and industry impact, and enforcing rules effectively, are also challenges.

Experts stress that regulation alone has limits and must be paired with digital-literacy education and guidance at home and school; designing technical blocks and educational responses together is important.

Children in Korea's Chinese families are in the same digital environment; multilingual digital-safety education and guardian guidance provided together could reduce blind spots.
