Due to my structure of roleplaying in the game itself, very few people actually know anything useful about Ghost IC. I think this is more so because no one has reached all the appropriate "flags", rather than me being an uncooperative bugger.
When I decided to launch my now hidden IC blog, I originally wanted it to expose all of Ghost's inner workings and that of the Foundation. OOC, I would've like for people to read my work and provide feedback on its concepts, design, etc and have fun reading it. I also thought it would have hopefully presented an interesting angle for others to be interested in the Sansha stuff.
I find it completely unreasonable to expect people to ignore valid tactical/strategic intel when it's presented anywhere. I disagree completely with people in IC RP using information about a person's thoughts, secrets, etc against them without previous interactions to 'justify' having that information. Note the distinct difference between tactical/strategic intel, and IC RP information I am suggesting.
This is an incredibly slippery slope for me to take my position on. To expand, I am of the mindset that unlike many other things in EVE, RP is a purely cooperative venture. If a person does not want to include you in their RP, you are not included. There is no way to force this or 'assert' yourself like in PVP. The only thing you end up doing is making yourself look like a jackass.
Thusly, for RP to exist between entities - hostile or not, consent and cooperation of some kind is required. The failcascade begins when 'malicious' leaking of private IC information is spread around. Bystanders may end up using that information without realizing it should not be within their grasp at all to begin with. The system breaks down and you are forced to privatize all your information OOC as well (or face the consequences).
It is this disregard of the cooperative spirit that greatly annoys me. To me, roleplaying is creating a story with others to tell. You can't make a good story if there isn't some kind of respectable cooperation going on.
To answer the last question, in light of my thoughts and some instances of my own goodwill being thrown back at me, I am very colored in what should be presented OOC for people to read or not. At the end of the day, you must assume everyone reading your information has malicious intent in mind. Otherwise, when a troll does come along and throw a wrench up in your grill it can be very damaging if the information given is sensitive to your RP.
