Modern advertising platforms like Facebook, Google Ads, Bing, and native networks are focused on protecting users and their ecosystems. Algorithms analyze dozens of factors: account history, payment behavior, creatives, landing pages, frequency of changes, and even advertiser behavior. Any deviation from a "safe" pattern can lead to limits, temporary restrictions, or complete account suspension.
Adding to the complexity is the fact that even when formal rules are followed, accounts with low trust are often subject to automatic penalties. Self-registration and long warm-up periods don't guarantee results, and with scaling, the risks only increase.
