Hey mate, fellow Aussie here in almost identical situation, minus the “anonymous” Facebook account. I have one from decades ago in my real name that I haven’t used except for 2 Marketplace purchases in the last 15 years. I’ve tried creating new accounts in fake names, on public Wi-Fi with no luck. In one case the account was flagged for review and never approved, and in the other I was suspended until I would upload a selfie (how about no?). Do you have any tips on how you established a ghost account in the first place?
