Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi all, my question is very simple.
Can lock boxes be picklocked without being opened or/ even better/ be picklocked without trading the boxe with the rogue? I know it was possible in retail vanilla, here rogues ask me to trade the boxes with them.

If I need to trade how do I know the rogue did not hide from me a blue or even an epic?

You dont know. Find a rogue you trust. By trust I mean: epics (think only highest tier boxes have em anyway) and blues are always in a box together with a green. Find somebody ou trust to not just loot the green and then close the box saying it was the only item.

Or push for a fix.

Or pay me some gold so I open it on stream for you

Cant they trade it back un-locked and not opened?

That why theres allways rogues yelling to open boxes, they can do whatever they want and no one will ever know.
Even in party with the rogue he can fool you with np, he just needs to not loot the blue/epic and give u the green.
This needs a fix thats for sure.

Ok tks for the info
