so, just discovered how sneaky sites get you flagged, and man it's wild. they check your headers, IP patterns, request behavior, even timing gaps and ua strings. like, they have scripts running in the background checking if your proxy headers match real browsers. cheaper proxies? forget it, they get caught fast. high quality residential or mobile proxies? way better at slipping past these checks but at a price. see the thing is, you gotta weigh price vs quality. low cost datacenter proxies? they might save you a buck but get flagged quicker than a noob. mobile proxies? costly but they blend in better, especially for anti-detection. also, some providers just slap a detection layer on their proxies, so always read reviews., you wanna buy the least detectable, most legit proxies you can afford, cause getting banned for bad proxies is just a waste of time. anyone got tested sites that really catch proxies? or better ways to stay hidden?
