While the thread is completely off the rails, I figure I might as well continue the detour.
We (Alliance Office of Statistics and the /r/EliteMahon subreddit) realised quite a while ago, that one of the likely reasons some of our expansions were heavily opposed, despite being nowhere near any other powers, was player groups. We spent some time looking for the "culprits", but a 30 light year sphere typically contains between 150 and 200 populated systems, which makes it a very daunting task to do so.
We want to talk to the groups, partly because we want to figure out why they're opposing us (maybe they misunderstood something and we can rectify it) and partly because we want to know what they consider their territory. If they want a 30 light year sphere without us in (and we're not there already of course), that's fine - but we'd like to know where that sphere is, so we can plan around it. Having these lines of communications is important, because it also allows us to explain, for example, that we'd like to use a system in their area as a CC sponge, but have no intention of trying to expand it. If they're okay with that, we go ahead, if not we'll find somewhere else.
Where it gets annoying, is when a player group doesn't reach out to a power to explain that they will be opposing an expansion and why. This is particularly annoying for me personally, when I'm suddenly asked why there are several wings of Mahon pilots opposing an expansion somewhere, and my answer has to be "I have no idea" and I then have to spend my time trying to put out diplomatic fires. I don't mind that the groups fly the Mahon flag (it makes sense - Mahon can oppose 90% of all PowerPlay powers), and even if I did mind it's not like I can do anything about it - I'd just like them to reach out to the power in question, either on reddit or on the PowerPlay forums, and preferably before the shooting starts.
