Just ram the jump charger repeatedly until they meet your demands. Jump requires your position to be static. Preventing folk from jumping out stalls the entire convoy, usually forcing 3 to 5 people to dock, and log combat characters. Flipside is you have to go point blank with the jumper - which is usually a capital ship.
Nova torpedo shower on the jumper is also funny. You can do it from outside the jump range, and it engages the jumper and usually a few ships that are close by it. Best effect is to wait until the jumper is charging. Some folk have fuel floating in space - shooting that fuel is amusing too and causes the jump to fail. Especially annoying if the base they are jumping from does not sell fuel.
Personally, I still feel that the group jumping of transports has created an exploit and should be prevented.
Wide awake in a world that sleeps, enduring thoughts, enduring scenes. The knowledge of what is yet to come.
From a time when all seems lost, from a dead man to a world, without restraint, unafraid and free.
