Malwarebytes Privacy VPN is a next-generation VPN that employs the newer and faster WireGuard protocol to give significantly quicker speeds than traditional VPNs. Malwarebytes also started operating its VPN service in 2020. But, like many other cybersecurity companies that have launched their VPNs as a security add-on. Malwarebytes is their flagship product and one of the best antivirus software on the market. From malware removal to device protection to ever-changing prevention, all solutions are reliable and trusted by millions of users across the world. However, their product has developed and transformed over time. A single individual founded Malwarebytes. is a cybersecurity firm based in the United States that safeguards computers and companies against malware and other internet dangers. The entire process from detection to block list generation and implementation could all likely be automated, and it probably is considering how much money Netflix has to throw around and how long they've been dealing with VPNs and similar tools used to thwart their region blocking and differences in content served to each region.Malwarebytes Inc.
Unless a VPN provider can somehow show sites their customers visit different/somewhat unique IP addresses there is likely no way to avoid services like Netflix from creating and using such block lists. It would be very easy for a site like Netflix to detect that numerous different accounts belonging to customers in different cities, states and even countries have connected using the same IP (one of the IP's belonging to the VPN provider, in this case, Malwarebytes) and so they likely then add that IP to their filter/block list.
Since they are probably using the server's IP address to determine that it belongs to a VPN, they are likely changing what's displayed as a result via a filter/block list which they compile, likely through telemetry.
I did a bit of research and located this article from Computerworld indicating that Netflix does indeed seek to block all VPNs and I also saw countless articles referring to the fact that Netflix blocks VPNs (often citing the issue I mentioned with possibly subverting their ability to display specific content to customers in their specific region).
