You are not alone. From mid-2024, Facebook will severely crack down on unusual activities, especially accounts purchased or using unsynchronized environments (IP, fingerprint, cookies, timezone...). Even if you do not spam, if Facebook detects an unnatural behavior pattern, your profile will be taken down soon.
The current solution is to optimize the entire ecosystem: from buying clean accounts (high trust score, clear login history), using personal proxies that have not been burned, to an anti-detect browser environment, warmup behavior that is slow and natural like a real person. And most importantly: do not re-use dead resources. At this stage, playing manually and investing in stable setups is better than buying in large quantities and burning continuously.
