Solid breakdown—especially the point about new accounts having almost zero room for error. One thing I’d add from experience: many “instant” shadowbans come from invisible signals like IP/fingerprint reuse when creating or logging into multiple accounts. Even if content is clean, that alone can trigger restrictions. That’s why I separate accounts strictly (different profiles, proxies, devices). Tools like AdsPower or gologin browser help with this, but even manual isolation goes a long way. Slow start + clean environment has been the safest combo for me.
