The issues been resolved. My Hutt is in hiding so your raid on my palace will be useless and chances of finding him 1 in a million. If you still care to look for him while he's hiding.
The raids will still take place whether Keddo is found or not, for the bounty is aimed at dismantling the organization moreso than the individual Hutt.
I don't think destroying an emptied palace of a single Hutt wil damage the organization all that much. It's a huge network, perhaps different strategies would work better in dismantling the conglomerate.
Right, the bounties on the Hutts that are being acted upon are by the Exchange and the Shadow Syndicate. This means that Desilijic Assets are being destroyed and taken over by these two criminal factions. And yes, they will persist.. and no, they cannot be retaken without IC effort.
