Have you read the first post in this thread at least? Abuse is addressed by:
1. Only Guard IDs can use this.
2. This has a cooldown time where you can't use it.
3. Possible monetary cost attached to using it.
Donutman: just closing the lanes and not allowing docking would be great, but I don't think you can be made hostile to just bases and not NPCs. After all, the bases are NPCs too, they just aren't ships.
i like the idea, only if it was attached to NPC factions with a base in the system. It'd make people stick to their ZOI more, being unable to call for help way from their factions base.
