The rest of the statistic is about driver's licenses specifically, including technicalities like expiration dates and address changes. The online ID check for age verification don't care about the address part anyway, in my experience.
If someone has an expired drivers' license or they changed their name and haven't updated their IDs, they have bigger problems than age-verifying their Discord accounts.
My driver's license was expired for 8 years until last year. I wasn't driving so the pressure to renew it was very low.
I actually only renewed it to get medical care and because renewing the license was only a little more expensive than getting an ID-only card.
It did prevent me from using some porn sites because my state requires ID verification but many sites just ignore the requirement so I just didn't use the sites that required ID.
