That just means that the IP you share with many other NordVPN users in Chicago and Los Angeles hasn't yet been put on the Cloudflare poor-reputation list that Internet Brands use as part of their general defenses against bad stuff.

Worth remembering that when you use a public VPN service the IP you break out onto the internet with is shared with many other users, some of whom are up to no good. The public VPN operators are good at pushing the perceived benefits of their services, and whilst evading geo-location based content restrictions and/or pricing, and some local/country based access restrictions are reasonable use cases; overall because of who you are sharing the service with its my strong suggestion that public VPNs do not improve your security posture to the services you're interacting with.
