The comment I responded to offered no such qualifiers.

To answer in general, aging of accounts is common as is synthetic credibility-building activity. There are marketplaces where you can buy sets of years old accounts with activity for every major platform. Anything you could come up with would either be so stringent it would exclude most users or be easy enough to become a target for account sellers.

To be honest this is why I got out of the space, it's sisyphean.
