Often times, there be In-Game Looting events, at places such as El Patron's Mine, Isla Tormenta, and The Catacombs, where you can grab a crew of people to loot at various places, or see Guide To Looting Gold for different looting suggestions. Plundering, for example, is another great way to loot if you like sailing.
Post below any events that you would like to organize.
I believe we should have a looting party when I get back from Hawaii in let's see like six days at El Patron's Mine in my guild server Hassigos. I hope to see you there :D
