Discord deactivated because of age?

"Hello,

It's very important to Discord that we provide a safe and friendly environment for our community. We've determined that your account violates our Terms of Service or Community Guidelines. Therefore, we've suspended your account for the following reason:

You have indicated that you are under 13 years old or have not yet reached the age of digital consent in your country. You can find out the minimum age for using Discord in your country here: https://dis.gd/age-gate

For legal reasons, we must enforce our age restrictions and therefore, if you appeal, we must confirm your age.

To verify your age, please take a photo of yourself (a selfie) that includes BOTH of these things:

1) A photo ID showing your date of birth

2) A piece of paper with your Discord username on it (including the last 4 digits after your username)

All information must be visible in ONE photo.

Once you've taken the photo, submit a request here: https://dis.gd/request and select "Update my age on Discord" under "Trust and Safety."

Best regards

The Discord Trust and Safety team"

I received this email this morning. My account is already two years old, and when I created it, I remembered saying I was 14, so I'm 16 now. But what do they want with my personal information, and why all of a sudden only after two years?
