I'm going to bring up something that seems to be a topic of RP constantly, and ask on public terms. There seems to be a lot of confusion about Stillwater's allegiances, and while I think I can understand the approach/logic you're going for here, I don't think others can, nor do I feel it to be a sustainable approach.
The idea is that Stillwater is secretly Angel Cartel, but publicly legit, correct? Nonetheless, there is publicly available OOC information about the Angel Cartel ties here and in-game, with no effort made to hide it. IC, this is denied, and there appears to be multiple player conflicts on the matter, with one side accusing the other of breaking the IC/OOC barrier.
The problem is, is that when the "secret" details are so publicly available (even if marked OOC), how can it be expected that using details such as corporation descriptions and titles is breaking the line? There are many IC excuses for this, such as GalNet searches, rumours, reports, and so forth. For example, when a completely newb RPer who has no idea what the barriers and boundaries are (after all, there is no written rules about RP) looks into Stillwater's IC corporate description, they go "Oh, they're an Angel corporation". When asked IC, they are told otherwise, and this would just confuse them as inconsistent, as it has done with many people already.
To use an analogy, it is like organizing a party game, where everyone already knows the answers and how to get the goal, but the judge is expecting everyone to forget about the solutions for the sake of the game. How can one ensure that nobody cheats, the same way one can't guarantee or hold someone to account for "breaking the game" when the answer is so clear?
In short, I don't think one can expect everyone to ignore the OOC details, nor can anyone be held to account for using the publicly available detail IC when there is no consensus or any written rules on what the IC/OOC divisions are. If it helps, I have previously supported the approach, what with the whole "The capsuleers may know us to be Angels, but the baseliners certainly don't". I think you're better off removing overt Angel Cartel references and keeping it internal. It just appears very confusing.
