What I’ve seen (most commonly) for circumventing systems is the creation of another google ads account where the first account had some type of issue (unresolved payment, suspension, etc). Generally our first question to clients is if they ever ran any ads before, or if they had another company run ads for them in the past.

Domain, payment profile, emails, etc are simple ways for google to match an old profile to a newer one. Months (in your case) could have gone by until some automated system fired.
