Well, alot of people who use it on Luclin have about 5-6 toons themselves that they box.
The process would be quite easy.
Kill the mob.
Check the loots.
Have the taskleader sit in the Bazaar and do invites as people pay for the loot.
Then have them get piggied into the zone.
Warp your cleric to Keldovan, Ture, wherever, and have them suicide into some mobs and then summon corpse and rez.
Obviously, one seal per mob, but who is to say you have all rots on every mob.
Rinse and repeat.
--------------------
Don't think a zone flag would keep someone from doing this, most people nowadays have thier signets, and if they don't they can jump next weeks train to loot land.
My point being, it's a little ridiculous that people are selling the loot now, and I hope that they do get banned.
