There's a wide gap between "completely reliable" and "completely

Well, since anything can be done to the referrer header (modify it or
not bother to provide it, and you have no way of knowing that what you
get as a referrer is true), it can't be relied on at all. That's what
I'd call a completely unreliable thing.
Now, if you would get it or not, and it always contained the right
information when you got it, then I might agree to say that it's
somewhat reliable. But something that's somewhat reliable isn't
something that you can rely on at all.
I shall refrain from continuing this recursive notion, before we all
disappear down a gravity whirlpool... ;-)
