It is a paid service that I what I am understanding from your post, pvacreator would not provide such service for free especially the main purpose is free promotion using facebook account so if one account is limited he uses another one for example to resume the situation.
Because most of people may use this account for promotional purposes not mean pay facebook ads but sending messages to people or even to for example use hootsuite in auto posting group while facebook did not open website for everyone placing their advertisements for free that is not main purpose...
I’ve been in the same boat before, and it’s definitely frustrating. If you haven’t already, maybe try reaching out to Facebook support. Sometimes they can give you more clarity on why the ad accounts are still disabled, even after the business manager review goes through.
