In most places, parents have to limit the time their kids spend playing games themselves. But in China, the games police themselves, locking kids out if they play too much.

From checking national ID numbers to scanning faces, Chinese games use a range of features to restrict underage gamers. But one group says it’s still not enough.

The China Consumer Association, a government-backed consumer rights watchdog, released a report on teenage myopia and online games. After testing 50 popular online games, the organization found that many fail to check real identities or limit gameplay time for underage players.

Only 17 of the 50 games tested required users to log in with real names, according to the report. In two of the 17 games that enforce real name registration, the association says they passed the verification with fake ID numbers.

Gamers in China have been required by law to sign up with their real names since 2010. It was only last year, though, that tech companies started enforcing the rules more heavily after authorities pushed for stricter control of online games, citing concerns for children’s health. Tencent and NetEase have since both introduced their own versions of anti-addiction measures that limit minors' access to their games.

As the largest gaming company in China (and the world, for that matter), Tencent has a lot on the line when it comes to following the country’s regulations. The company’s two biggest blockbuster games, Honor of Kings (aka Arena of Valor) and PUBG Mobile: Exhilarating Battlefield, were among the 17 games that required real name verification.

In addition to checking players’ IDs and real names, Tencent is using facial recognition to identify them. It’s also testing an option that bars everyone under 16 from playing Game for Peace, its new version of PUBG Mobile.

NetEase hasn’t started matching player information with police databases like Tencent, but it recently started allowing parents kick their kids out of a game at any time. Both NetEase and Tencent have curfews for underage gamers in some games.

However, they still both have games on the association’s list of offending games. Popular NetEase games Identity V and The Day After Tomorrow are named for not enforcing real name verification, while the Tencent game QQ Farm doesn’t have a time limit for underage users.

The association also says that after reaching the time limit and getting locked out of one Tencent game, they could still log into another game from the same company. Among those surveyed in the report, 30% of minors say that they use another account or play another game to get around anti-addiction systems.

Tencent and NetEase have not responded to our request for comment.

The report also says that some games are asking for too much information from users. Three of the 50 games tested requested access to call logs, and one requested read and write permissions for the calendar.
