Question on Grimrot loot rights

[TheFishyOne]

'ey, I've seen a LOT of folks recently camping Grimrot with high level toons that can't use the Aegis of Life, so that they can log onto lowbie Clerics who can't kill him themselves, and loot the drop. Given how exceedingly rare Grimrot is, I, personally, don't think this is right. So I want someone else's, preferably a staff member's take on this, but if a person kills Grimrot and then logs for any reason without looting the corpse, are the loot rights now FFA?

Just want to know, before I potentially make a ninja out of myself.
