• Buy, rent, recover, and manage accounts from various sources.
• Work with pixels and conversions: creation, setup, audience transfer, backups.
• React quickly to bans and switch to backup infrastructure.
• Adapt processes to Meta policy updates and platform changes.
   

Requirements

• 1–2+ years of experience in account farming / warming.
