I found this in my Nginx logs, they teached marketing to all of us

I was earlier today reviewing some logs from one of my Nginx instances and found the following entry:<p>``` 401 GET &#x2F; Expanse, a Palo Alto Networks company, searches across the global IPv4 space multiple times per day to identify customers&amp;#39; presences on the Internet. If you would like to be excluded from our scans, please send IP addresses&#x2F;domains to: scaninfo@paloaltonetworks.com ```<p>I think it is just genius. It is a demonstration of effective marketing and knowing where your audience is.
