This assumes people are putting in their real birthdays, which IMO is a terrible practice to encourage.

I never put in my real birthday. It's just one more datapoint to leak in an inevitable hack and help scammers exploit me.

Just because a website sticks a field on a form, doesn't mean you need to fill it out.

I can think of maybe 1 website I use that has a legitimate use to know this info about me... and a dozen that use my fictious birthday for no other purpose than an excuse to market at me under the shallow guise of a 'Happy Birthday' email.

There are many websites that believe I was born on January 1st, in a year close to my actual birth year.

When it's actually required by some law or regulation (e.g. financial stuff) I give my actual birthday. But when some site is just wanting to comply with age verification? Yep, I'm over 30, so you don't need to see my identification. (Jedi hand wave).

		Well, they would have the legal right to force-choke your account, or chain your partner to a golden bikini, when they discover that you weren't abiding by the Terms and Conditions which you agreed to. Seems fair.

They were not, actually.

IIRC, it went like this: the account creation screen prompted them for a birthdate. They entered a fictitious one and pretended to be over 13. (I saw my niece do this in front of me, and I just sighed a very heavy sigh. She was way more interested in Club Penguin.)

Then later, they let the cat out of the bag. They tell their friends "lol I'm only 10! Today's my birthday, so give me a hat!" or something. And so if they claimed they're 10 they got 3 years suspension.

I think there was never any verification done, and no verification was possible: think about it, under COPPA, a service in the USA cannot collect PII from children under 13, so what do you do when a kid gives you two contradicting datapoints? Err on the side of caution.

I gave Yahoo! a false birthdate when I signed up. I was 27, but I also just felt they weren't entitled to knowing it. However, I soon found that maintaining a fraudulent identity is tiresome and error-prone. And Yahoo! wouldn't let me simply change my birthdate as often as I wanted to.

I once had a conversation with a friend about cheating on IRS taxes. She said "can you lie to a piece of paper?" like fudging numbers wasn't like lying to an auditor's face. It was a rhetorical question, of course.
