Well some people seem to have the problem with their Megaupload links or some other upload hosting service (mostly Megaupload though) seeing that their link are from this site which they then delete the file knowing its from this site.

Sooooo in order to keep them from I recommend you use something called anonym.to this helps keep webpages from tracking links as refers Here is a little info about what it does:

The advantages of anonymizing your external links with anonym.to are as the following.

People can use this tool to prevent their site from appearing in the server logs of referred pages as referrer. The operators of the referred pages cannot see where their visitors come from any more.
Using the referrer removal service is quite easy.

Example: Lets say you have a soundtrack uploaded to megaupload right? And normally they delete files since they see that their log files log this site and know something is fishy about the link

so lets see you want to anonymize it right to keep them from logging tihs right well simple just pasting this before your link " http://anonym.to/? "

so your link will look something like this http://anonym.to/?http://insertlinkhere.com

Well I hope you find this useful for keeping links from being deleted
