Ok so what happened was a few weeks back I got hacked on my discord. My discord was hacked for clicking a link and I trusted a friend. The hacker tried to brute force into my Gmail but I managed to change my password for my Gmail just in time as well as apply 2fa. Long story short I got my discord back through tech support about 1-2 weeks ago and for awhile I thought everything was fine until today. Google notified me that my account was underage and that I can recover it by providing drivers license and all that. I think the hacker did something to my google account and I thought it was secure. I even added 2fa and everything. My question is if I were to provide my id or card to change my age will the hackers know? And FYI I wiped my computer free of any malware.
