Interesting test suite, thanks! I have tested scrapeninja.net via https://scrapeninja.net/scraper-sandbox and I got { "puppeteerEvaluationScript": "OK", "webdriverPresent": "OK", "connectionRTT": "OK", "refMatch": "OK", "overrideTest": "OK", "overflowTest": "OK", "puppeteerExtraStealthUsed": "OK", "inconsistentWebWorkerNavigatorPropery": "OK", "inconsistentServiceWorkerNavigatorPropery": "OK" }

and ip range of "us" geo proxy gives is_abuse: true. Consider this to be okayish though, given that this is a default proxy pool.
