I don't know where you clicked, but I can assure that all useful links are working - and if they don't the general way is to report a broken link by PM to the uploader.
Usually a dead link is fixed then within a day or two.
RS is useless as the files will be deleted in a few days, hotfile is used by some uploaders.
You can not force someone to use a specific hoster for the uploads, be glad that people share the files at all
It is hard enough to find hosters that keep files alive long enough to use them - this is especially true for IGO related files and new maps in general.
