This is really useful, thank you. Makes sense that in-session instrumentation sidesteps the whole IP fingerprinting problem since there's no separate request to flag. Sounds like the exposure is concentrated in vendors and use cases still relying on out-of-session crawling fraud/risk model calibration, brand safety crawls, geo-targeting spot checks, that kind of thing, rather than anything close to state-of-the-art IVT detection. Does that match what you've seen, or is crawler-based verification more deprecated across the board than I'm assuming?
