Discord age verification and update

I'm concerned about my lack of protection online. I've faced false reports on three accounts in the past, losing three servers despite providing proof of my age. Thankfully, their timely response saved me this time.

Does Discord retain a user's date of birth after the initial age verification to prevent future bans? I aim to steer clear of undergoing a similar experience in the future.

Like if my age has been updated from being falsely banned, and someone reports me for being underage again in the future, can they check if my age has been verified?
