Most cloaking setups are getting torched within 48-72 hours now because both Facebook and Google have moved to real-time behavioral analysis that goes way beyond just IP detection. The platforms are running actual browser automation to crawl your funnels from different geographic locations and device types, so static IP-based cloaking is basically dead.
What's working better is dynamic behavioral cloaking that analyzes mouse movement patterns, scroll velocity, and session duration to distinguish between human users and platform crawlers, but even that requires constant updates to the detection algorithms and most people don't have the technical resources to maintain it properly.
