I look through the report of broken downloads (submitted by the users) every three, four months - all links are tested through the CSM as well as copying the link directly in a browser. If it gets no response twice it will be removed. Broken links are annoyance to the users and will be removed independently of the prog they are linking to.
If you submit links to LDraw.org just check them from time to time and don't forget to update them when moving to a new address.
