How about a lik bot checker

[exdiogene]

After some verification it seem that this code have enough differences from the original code of "DMan" the original author of the "linkchecker.php" script.

The author of this code have given the autorization to use its code as we see fit with no copyrights at all.

So there is no problem for me to test if it could be used on its actual linked sites and enhance it as needed.

But like many other link checker as this one, very often the link verification stop working with many of the predefined sites.

Anyway, it still can be used as a good starting point!
