Here, hope this help if i write it this way intead.
Read their news:
“Starting with VRChat 2023.3.3, creators must appropriately label their content via the VRChat SDK or the website. In a release soon after, players will be able to filter the content they see in VRChat based on those labels. If a player is under 18, the content filter is enabled and cannot be turned off.”
That means there will be a way to set what age your account is prabably more clear at VRCchat’s end since that is well how the system is built buy knowing a users set age.
prevent underaged people from getting onto the platform its at least better than none at all and could help keep some kids at bay and help parents from their kids getting onto it
But…
The platform is built to cater for people 13+, by knowing that it does not make sense to have warnings to try scare away their target user base from using the platform just because they are under 18.
Your looking at this form the wrong angle I believe honestly reading you state “prevent underaged people from getting onto the platform”
There is no fundamental logic in that more then everyone knows content creators can create more then what we might wanna see sometimes, therefor the new label system is probably being enforced, lets asume that without being rocket scientists ok.
So if it gets on the appstore/play store means only people with a google or apple account with right age set can actually download it for starters, that is your main age check.
And its parents resposebility to acctually be parents and set their kids accounts correctly so they cant download above rated content.
Then on second hand vrc is enforcing the people to set their custom content that are sugestive as suggestive so people under 18 cant view it also ability for us to report users who dont st it correctly.
But the reason why a promt also would not logically make sence is because someone who got an acocunt listed under 13 on a ios/android would not be able to download the game to start with and those who can, since their parents are lazy and set their kids ages to 16 or 18 making their accounts of legal age to access the content will do download and enter without parents getting a notification as well.
If someone is 13 or over and download a free game on a mobile, no parents are going to get a notification saying “oh no, your underage kid is starting up vrchat, here is a link for more information…” lets be perfectly clear on that, so its simply a fundamentally flawed idea.
If above is done correctly then filters and hopfully a more extended filter option for people who only wish to see/interact with people 18+ works.
And if a kid are listed as adults that are under 18 can get reported for an id check it would be good. <------ See that is what is missing, so people who dont wanna be in contact with underaged people at all does not need to.
The reason why ID checks are hard to implement online for starters are that every country more of less uses their own ID verfication for online services and versions of social security numbers etc.
So it relays on pretty much entering bank card information and then agreeing in a spesific local banking realted app.
Introducing but not enforcing a non-fee option to do that in order to mark accounts as adults, would be lovley. to set our account to be legal age in order to only interact with eachoter.
(not everyone wish to enter bank card info online, some just wanna play for free and some kids does steal/"borrow parents banking infomation and use online.)
Enforcing tho that practise so only people who can enter a bank card and verfy their age as adults to shut out people under 18 = That is not going to happen as the current target demographic audience is everyone 13+ by the looks of things, else they would have listed their game for 18 already and not the legal ago to create an online account without parental supervision.
