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.
All of this can also be (verifiably) disabled by the end user in the web control panel.
The part that seems shady to me is how you do this without being caught by the up database providers are marked as a non-residential ip.
What steps, if any, are you taking to make sure you are sourcing your residential proxies ethically? Honest question.
