All you folks do not have a grasp on anti detects and especially on proxies, the sooner you accept that, the better.
Do all the sellers here know how the subnets and ANSs are maintained or how contaminated they are at any given time?
Lets bring the arguments, the hard questions.
So you say residential proxies "are good" . What makes you think so? Did you check their exit IPs, do they abide by the sticky session time promises, how many other machines use that same IP, you wager? How many of them been seen before , or worse, after your account creation?
Static ISP, do you all know how these are created? How these work under the hood? What they are?
Mobile proxies, so what are you gonna do with your mobile proxy, you gonna run them on an anti detect android emulator?
All the statments here "provider x" did never let me down are subjective and have very little credibility.
It is part of my business to check proxy providers, I have bots to do so and my own tools, and let me tell you what is out there is not good, not one provider can be trusted to plug and play, not one, theres differences in exit ip quality as far how badly they have been flagged, but all this does not fix the ecosystems inherited problems.
