How does URL Encoding protect a mail address?

[patrickfav]

As far as I understand this liquid filter will just url encode the email address. To me, this kind of defeats the purpose as it will only get harder to read for humans, but is still easy to read for machines - so basically the opposite of what is intended?

Isn't the only way to obfuscate the mail to use some naive javascript obfuscation so it is not visible in the source of the HTML?

Here is a gist of a simple plugin I made for my page with another implementation incorporating some tricks mentioned in the blog above:
