Go for it, just don't expect many friendly responses from people who know you did it.
I've had people attempt this before, in regards to the [KoF]'s armoury:P
Armourer took back a gun I had pirated from it in return for a weaker one (Lots of KoF ships around you influences things) and as soon as the deal was done, he said to kill me.
So, ran with the gun, later got the armoury again and pirated the first gun back off him.
Basically, he lost more than he should have for being silly.
