Hmm, we should probably clarify the rules on this. As I imagined it, the rule implies the obvious stealing in cases where the character is around, like fx people snatching items from those that have their stock on display in the Western Outskirts. Snatching someone's items and gold as he is bleeding out or just died probably should be considered the same thing - especially if his allies are about - but when you stumble upon a deserted backpack and items, I feel it should be fair game.
Sounding reasonable?
Very. Honestly just put in USE COMMON SENSE!
These the guidelines I follow normally:
Low level/noob - Leave it, they are probably having enough trouble getting use to the server.
Huge Outskirts fight/Huge fight - Leave it, there is so much chaos going on probably, no one wants some jackarse stealing everything on the ground while people fight.
Stumble upon random stuff - Take it, if it's in your character to do such a thing. If it looks like "noob/low level stuff" and you really have no use for it, see if someone is around.
Stumble upon bunch of stuff but all ghosts of characters are all still there - Leave/Take. I would if it's IC to do so, but I would send them tell saying all take there gold or try work a agreement so I can stay true IC.
High level - ROB THEM BL- *coughs*. Leave/Take. Send a tell to them, most high levels are mature enough players, and most don't mind losing some gold/items. (Which could be small fortune to a lower level)
And finally Communication - Everyone knows this, but just sending a tell if you think the player might be upset goes a loooong way.
Some guidelines I normally try and take. Not suggesting this to everyone, just throwing it out there.
