I think you're missing the point so let me ask you a question: How did you feel when you found the hatchet?
That being said some servers don't get rebooted often enough, if all the loot has been taken and there is nothing left but trash it's time to find a server with an active admin. Good servers get rebooted every 6 - 12 hours, some every 4 hours (great for finding chopper crashes). These servers have weapons on them because the loot piles havn't been cycled into junk.
But even on a server with only junk you can pick up the trash and drop it outside the building and wait several minutes and more loot will respawn but you have to clear the piles completely. It may be more junk but that's the luck of the draw, keep at it and you will get something.
