Tuco Salamanca and Jessie Pinkman are mine.
On daily basis, I am soloing the Slags in the WH to loot the end container. It is true that I use Jessie to aid me in my PVE efforts.
According to the rule here
Here is a list of some actions that we consider unfair and illegal in the game. If you're spotting someone violating the rules, feel free to message an Administrator by typing: +requesthelp <message>.
Using multilog or bypassing relog timer in order to gain an advantage in PvP activities. Also includes scouting and looting.
and since at that time neither Tuco nor Jessie were engaged in PVP with akumadio there, who was just waiting for my combat with multiple Slags to end so he can "blue-suit vulture" the good stuff (he does that every day, which is perfectly legal) I don't consider using my alt to pick up my other character stuff to be action against the rules.
Since there was no PVP between akumadio and me, in this case my alts were not used either for PVP-related looting nor scouting.
Since akumadio of course was able to vulture Tuco for that armor later on (which is fine, regardless of what I think of such players), at least now he can stop crying about it, but IMO the rules were not breached.
