Not really, Meta for example is publishing those in their 10K but is doing on their own definitions of active users, if it were for Coinbase they could also do the same, judging an active user by a random time and sum, somebody who has logged, somebody who has tarded at least $100 in 90 days and so on, somebody who has a positive balance etc.

Anyhow, I've logged in to my Coinbase account again to see how it looks.
Seems like I have a  $5.4 balance from probably an airdrop or something as it's probably in some shitcoin not even shown on the main dashboard, I'm definitely not completely verified since there is one huge red banner there asking me for proof of address but still no message, no alert that my account might get disabled although it is restricted till complete KCY but it has been like that from at least June or July last years as far as I remember. So it's probably something completely random.
