according to Gamefront's policy:
New deletion rules for registered user files.
These rules will go into effect on July 19, 2012. After that date, files uploaded to a registered user account will need 1 download every 60 days to avoid deletion.
If a ?user file? is not downloaded at least once in a sixty day period, it will be automatically deleted due to inactivity.
If a user file receives at least 1 download every sixty days, it will stay on Game Front indefinitely.
This rule will affect new files you upload, as well as files you already store on the site. After July 19, 2012, if files uploaded to your user account have not been downloaded at least 1 time in a 60 day period, they will be deleted.
