Dead link auto-removal

 Because dead links are *so* annoying...
 
(0) 		  [vote for,

I hate following a link on site and getting messages like this:

//Article not found

From Wikipedia, the free encyclopedia//

I'd like a program that, when you load a page, automatically detects and follows each link on the page. Any that don't turn up results are visibly marked so you know it's dead before you waste time clicking on it. At the same time, a message is sent to the site's administrator requesting that the link be removed or updated. If a link that was previously marked as dead has been updated or restored, then it is marked differently.

Greasemonkey script: Linkchecker http://www.xs4all.n...script/Linkchecker/
Greasemonkey is a Mozilla Firefox extension; this is just one of the many, many things people have done with it. [jutta, Jan 14 2007]

Firefox Extension: Linkchecker 0.6.1 http://www.kevinfre...nsions/linkchecker/
Not to be confused with the script above; this one does roughly the same thing, but is implemented as a direct Firefox extension, without Greasemonkey. [jutta, Jan 14 2007]

       Cool idea, but I think it would really take a long time to pull every link on a page, especially if the page has many links, or if said links are burdened with much data.

       Man, google's going to get a shitload of email that way.
  

       Also add a way for the users of this feature to (a) share good redirects - it's often not a lot of work to find the updated URL, but why should it be done more than one; and (b) to mark links as dead that aren't technically dead, but that are little more than zombies, with the site redirecting to its root or a search engine on not-found, or the domain name having been taken over by a generic ad hosting service.
  

       Call it the Joy Link Club.

       I'm sure i've seen a system that can tag dead links in this way.

       Might a browser be configured (I'm thinking some sort of FireFox extension here) so as to display some message on mouseingover a link? (hopefully without having to load the entire page in order to so) - a positive response from the serving machine providing a different indication to a negative one.
