Please forgive me for asking, but why? (sorry if that's lame, but I really don't get your meaning from the context.)
I'll admit that I'm not an admin, but why wouldn't I want to make sure the links are good on a site I frequent? Wouldn't it save me some time to avoid the bad ones up front?
It's not your job to check the links of someone else's site.
The link checker doesn't respect the Robot Rules, and will wander blindly
into robot-hostile territory.
You wouldn't believe the number of lamers that come check stonehenge.com's
site hitting thousands of robot-hostile URLs because the first few versions
of this program had a live URL pointing at my site. I finally put a very-early
block in my website to keep people from doing it. And it still happens!
And I no longer use live URLs in my examples. Some people are just Lacking Clue.
