Using aged accounts is a good strategy for improving the stability of Facebook ad campaigns, as new accounts are more likely to face restrictions due to Facebook’s monitoring systems. Aged accounts have a history of engagement, making them less likely to be flagged. To find reliable aged accounts, buy from reputable sellers with positive reviews, ensure the account has a clean history without bans or restrictions, and use proxies or VPNs to avoid IP-related issues. Start with small budgets and scale gradually to build trust with Facebook’s system.
