Firstly, this post comes as a surprise to us, I think it's common courtesy to speak with the respective official faction first, listen to what they have to say and then post a request or do whatever you think is best.
Most factions on this server have a set of "archenemies" which they are able to hunt Sirius-wide. With a staggering 8 years of history between the two factions, we have one of the longest and most animose rivalries in the history of DiscoveryGC.
Also the claim that LH ID can attack IND without a demand is untrue and incorrect. In any case we are always interested if you wish to contact us as we will listen to your ideas and concerns as well as seek out a common solution.
(edit) Clarification: By current ID restrictions a Lane Hacker can only pirate IND transports anywhere in the Sirius and BUT NOT attack them on sight as it can only treat as combat targets transports hauling gate and lane parts.
