so, i keep seeing people swear you need those expensive anti-detect browsers with residential proxies for any serious scraping. lmao. just ran a two-week test scraping a notoriously aggressive affiliate network dashboard. used three setups: 1) cheap datacenter proxy with a basic puppeteer-extra stealth plugin, 2) mid-tier residential proxy with the same setup, 3) that fancy 'stealth' browser subscription paired with isp proxies. target was 10k requests per day per setup. the results are stupid. setup 1 got blocked after about 4 days, which i expected. setup 2 lasted 11 days before partial blocks. but the kicker? the premium stealth browser and isp proxy combo got flagged fastest, at just under 72 hours. my theory is their javascript fingerprint is actually too perfect, it lacks the random noise of a real browser. google's core updates are mostly just a game of footprint whack-a-mole for smart operators, and this feels like the same thing. my numbers show the sweet spot is a decent rotating residential pool with light, randomized fingerprint spoofing you control yourself. paying for that all-in-one 'undetectable' solution seems to be the quickest way to get your ips burned. cool story, bro, but my data says stop overthinking it.
