I built one, I just haven't made it available since it is customized to fit the needs of my clan and not very configurable.
Try it at your own risk! This is an unfinished script and hasn't been updated in a while. I used to run it once a month on my clan but I haven't in a while. Requires My Function and Item libraries (follow link in sig)
It is designed to loot everything from your clan stash and then autosell or mallsell everything in your INVENTORY. You should be karma exempt to use this.
You need to edit these two lists in the Item script to fit your clan's needs:
ClanKeepList(); these items are kept in the clan stash
DontSellList(); these items are not processed
I also use it for contest looting so when it asks you for an input enter 0 for a full clan loot. It will also create and donate dense meat stacks back to your clan over 500K meat in your INVENTORY.
If in doubt don't use the script!
