Last year SF suffered an attack of this kind where an infilitrator gave out our voice details and killboard admistration data. We had a couple of crazy days with people using this stuff to impersonate our members and directors and spamming the resources to damage our organizational integrity. We considered it beyond the pale for respectful RP interaction.
A lot of RP organisations (including my own) have a policy against using information that we consider to be OOC (forum logins, Vent passwords) or that has been gained by what we consider to be OOC means (infiltration alts). I understand that for a lot of people, including RPers, this is part of the metagaming fun of EVE, but for us it's a lot less fun than using our characters to ICly gain trust and information.
Of course, we're aware this doesn't give us immunity from others using the same means against us, both RPers and non-RPers, and take the usual precautions.
I'm aware that ICly I should probably read that material, filter out the OOC, so Cia(c) can be informed, but my overwhelming feeling of 'meh' prevents me.
As Mammal said, kudos for handling it with class.
