Anyway to keep allies from roaming around your systems?

SJ is right, but if you attack another human player's ship that you have a treaty with, I would think he would either declare war on you or at least go after your ships or else send him message to stay out of your system and see how he reacts and react according to his response. If he thinks your stronger, he may just back off for now. Try the intl like SJ said along with some diplomacy

just some ideas mac
