I have a number of links going back several years. I'd like to prune out or repair, if possible, the broken links, that is, the ones whose address has changed or no longer exists. Is there any easy way to tell which links are broken in Delicious so that I don't have to examine them one by one?

are the links public? – neo Jul 1 '10 at 11:28
@neo - yes, I think they are all public. – tvanfosson Jul 1 '10 at 11:40

There are a few tools available for download:

Those aren't online based but out of the last one it would be easy to build a web app ;-)

Unfortunately, what happens with most dead links these days is that they end up pointing to domain squatters rather than actual dead links which return an error when you try to get them. – delete Jul 1 '10 at 12:18
That of course is a problem. At least the perl script should be quite easily tweakable to detect this. – neo Jul 1 '10 at 12:24
How can you detect a domain squatter with a script? – delete Jul 1 '10 at 14:02
@Kinopiko: You could probably detect known squatters based on some distinguishing characteristic of their pages. I'm not sure how reliable it would be though, and maintenance could be a nightmare. – Matthew Crumley Jul 1 '10 at 14:17
We can detect pictures of a girl with a rucksack. – delete Jul 1 '10 at 14:20
