I don't know much about VPNs but that statement is one of my red flags: when a VPN provider is vague about ip reputation migrations I assume they're buying residential proxys.
We do use those for geo-unblocking, but they're not used for anti-CAPTCHA mitigations. We own and operate special purposes ASes and IP prefixes for that.
All of this can also be (verifiably) disabled by the end user in the web control panel.
My read of GP's reply is: they use residential proxies to get around geo-blocking, and separately have special purpose ASs to avoid captchas. They're separate solutions serving separate needs; connecting to Netflix gets you the residential IP, regular browsing would get you the other one.
All of this can also be (verifiably) disabled by the end user in the web control panel.
