Because as I said many will use proxies, and you will never know who linked to you.
any visitor not from an approved link gets redirected.
If a news website writes an article about you are you going to charge them too
yes, yes, yes, you want to send someone to my content you pay, otherwise don't send them. simple enough.
If the link stopped working I would remove it and no longer send you FREE traffic
and your users would no longer have access to my content/resource, a loss to you or you would have never linked to my content/resource in the first place.
Alternatively, I could link to google.com/q=yourURLhere
and it would be redirected as it would not be an approved link...
