As someone who plays the game, the first one is exactly like it sounds... The email specifically mentions loot containers on Ilum so it's not the PvP exploit you guys mentioned. Lower level players were dying/corpse hopping to loot containers on Ilum (level 40+ zone) and camping them. We're talking about standing there for hours and looting them repeatedly. Some may call this fair play but BioWare apparently doesn't feel that way.
