If you landed on rr3---sn-8pxuuxa-nbo6k.gvt1.com, you're probably looking at a Google infrastructure server, not a website that sells or collects anything. The page returns a 404 error, which is normal for a server that doesn't have a public homepage. The domain is owned by Google (gvt1.com), the certificate is from Google Trust Services, and the server uses modern encryption. The one blacklist listing is a minor concern, but it's common for dynamic IPs used by large networks. Since this isn't a business you'd buy from or sign up for, there's no real trust question. If you're seeing this URL in your browser, it's likely an internal redirect or a broken link from a Google service — nothing to worry about, but also nothing to engage with.
