Before NY was no PvP zone... haven for smugglers .
Players you want ban will move their caps to another system.. and we are back at the beginning... No point in banning anything. I know you are probably frustrated because when you want o have fun from nowhere 2 Libby GBs one or two cruiser and 1-5 BH Gun ships appear, or vice versa, few Rogue GBs with Dragonfly missiles and one Outcast dessie, but banning caps will not solve your problem.
You can do that by retreating and spreading propaganda in their face from safe location. Also, you should learn not to be so angry when someone rips you apart in your little ship. That helps -a lot-!
