This seems more like a PSA, which is good to know. And hopefully attract defender types to keep an eye out, but a ganker can shoot from such a vast space, it'd be tough to catch them out. How about extend the no weapons zone to 20 kilometers, whatever the autopilots drop-in distance is? That'd ruin the fun of trying to outrun others though.
I'd allow gankers IF they have to wear a Dork T-shirt logo that's displayed on their G5 heavily engineered killboat.
I made a suggestion years ago, that there should be 2 types of interdiction devices.
One is similar to the one we have, but in fact much easier to evade the interdicting beam. Using this one, essentially, if a commander doesnt want to be interdicted, they'll evade it. No having to fight the limits of your ship, just turn off-course a bit, and you evade it.
The other one is exactly the same we have now, which has a higher success rate of actually pulling another commander out of supercruise, but if your ship is equipped with this type, it sends a signal, visible from the space map, of where it's being used and maybe who's using it? Their ship at least? Gankers would have to use the second/current interdiction device to be able to pull an unwilling commander from supercruise, but everyone would be able to hunt for them easier. But how be the price for the gankers interdictor should also be 1 billion dollars, muaahhhahaha, but yes, they'd get a sticker for their ship and maybe a t-shirt?
