No, they'll claim they have a "legitimate interest" to keep some of it, and then use what they kept as justification to ban your new account too.

I think for this to work, Google actually has to delete any information about you completely from its systems. I'm curious if anyone tried this with success as well.

GDPR does not fix this situation. There are cut-outs in GDPR that allows companies to store data for longer. Financial/billing/taxes fall under that category.

GDPR doesn't prevent a company from retaining records of individuals who defrauded them.
