If you're concerned about referers, I recommend installing Referer Modifier and setting it to remove cross-hostname referers by default.
I've been using it for years and only had to add about 20 exceptions, like:
----
target: imgur.com
origin: -
action: replace
replacement: https://imgur.com/
----
target: amd.com
origin: -
action: target
----
target: google(\w+)?.com$
origin: google.com
action: prune
