I discovered my browser attempting to download this JavaScript file from google.com unexpectedly from a page serving a video embed from youtube-nocookie.com. It contains a base64-encoded contact email address and suggests it is some kind of Anti-spam script.

Excerpt: “Anti-spam. Want to say hello? Contact (base64) Ym90Z3VhcmQtY29udGFjdEBnb29nbGUuY29t”

Contents of script: https://pastebin.com/CD5R0tgy

Is anyone familiar with this script? Thanks.
