What Is Linkbucks/Linkbee?

As you might have noticed I've opened a poll to find out whether you like or dislike the 'linkhiders'. I saw that a few people allready voted that they don't know what it is. So I'll explain. At the moment I post with the downloadlinks, for example http://rapidshare.com/files........ When you click at that you go to rapidshare and you can download the file. Link reporters spot that very soon and that is one reason why the links are dead so fast. I hope I can stop/delay that by using Linkhiders like Linkbucks/PbUrl/Linkbee. Then you'll see a very short URL, if you click on that you will still go the rapidshare page to download the file but you can't see Rapidshare standing on my site. So that's why my links might be alive longer then now. For example: http://8cca1cde.linkbucks.com http://linkbee.com/E5OI7 If you click on one of those you will see how it works. The link doesn't mention willempiesblog, but you do go there. Hope now it is more clear to you guys ;)
