Minecraft:

while this is only in places where you must have age verification, im still gonna list it here.

theres mods on modrinth (No Chat Restrictions), and this site: https://nofacescan.app/

Discord:

right now, the only known method to bypass discord age verification is this (currently patched, risky,) site: https://age-verifier.kibty.town/

as of now, discord says that one of the ways the bot auto verifys your age is checking weather you have bought anything, and because you must be 18 to get a credit/debit card, it will automatically think that you are an adult, and most likely wont ask you to verify.

Youtube:

there currently are no known methods.

Roblox:

theres this site: https://nofacescan.app/ and you can use images of different head positions and point your camera at it.

Windows, MacOS, And Linux:

based on avaible info about OS age verification, you will only need to input a birth day month and year, so you can just lie.

if you find any methods or any platforms you want me to add, email me at mobitsgaming@gmail.com
