If your ship has a docking bay, my preferred method would be to kick a smaller ship out, with the items on board, and just add people to the crewlist of that. Then dock it again once you've scanned to confirm they've left. But maybe that's just me.
If you simply enter a vehicle in your ship, you're effectively trapped if they decide not to leave in a timely manner.
Nevermind, just saw it was a Y-head.

Not everyone can be online 24/7, though.. If you are in a vehicle and tired of waiting, find out log in times of people who are onboard, and when you're sure they're offline, go to cockpit, start hyper and return to vehicle.
Of course, you hyper to friendly territory and before you get there, you contact local government and they assemble a strike team to board your ship after you transfer it to them to arrest people onboard.
And, yea, I know I sound megalomanic and all, but I guess that's what I'd do.
Scamming is such a harsh word. I prefer to use proactive redistribution of assets
