For several other link-protectors such as share-links.biz and socadvnet use this website:

I'd also highly recommend using jDownloader to enhance your anti-piracy efforts. It can check whether the links are active or were removed for most of the tubes and file lockers, which helps alot if you have to send lots of DMCAs. Instead of checking all links manually you can simply copy them into the clipboard, jDownloader will intercept them and check - if there are any links that were not removed you can easily export them and send new DMCAs.

There is also a very useful Firefox plugin called Rapidshare links checker. It will check links on the fly for a wealth of file lockers (not only Rapidshare) and will add red/green circles next to each link to indicate whether it is active or not.
