Is it no longer worth it to send military ships to expeditions to create debris?

I've noticed that a few players in my server seem to be sending military ships on expeditions frequently (a large amount of debris occasionally appears at pos 16). Is this confirmed to no longer be profitable, or does it depend on server settings?

On this server, a normal expedition (4-5k LC, 1 reaper, pathfinder, probe) costs about 28k deut.
