At least they got their account banned after performing some action, I got mine blocked after 3 years of no use, it was just standing there without money or ads.
I started receiving warnings about mine, which has been unused as far as I know for maybe 10 years. Out of curiosity I tried to login to that account to see what site was using my old adsense code and was unable to login without adding a phone number, despite verifying through my backup email account.
No thanks Google.
