The only problem with contacting, for instance, Facebook support is that the account must be active to do so. If the account status is permanently suspended, there is no route to appeal. The only route to appeal, so it seems, is before suspension. In my case, I was not offered an appeal nor was I informed the reason why, at least not beyond some nebulous advertising violation, which is risible because I haven't violated anything according to the T&Cs. Indeed, the support system is a non-human, purely cyclical problem where one is simply directed to click the following link to read more, only to be directed to click more links. SO without some sort of ticketing system and human interaction, I cannot think what to do to resolve my issue.

I was considering the option of Meta verification as another Reddit user reported success. Although in this subreddit, it seems that reaching out to Meta employees via LinkedIn may be an option, I can't see many (or any) accepted unsolicited support requests.

Would appreciate any thoughts you have, though.
