Many of you might have noticed the change to the chats in Eve and that they have become less stable. One of the changes was to detail all people in a channel. Now think about that for a second.
As soon as you log in you will show up in a chat channel, people can scroll through the channel to see if you are there and this means by default they know if you are online or not. So if you are under a war dec in hisec or being hunted as you are in a Titan or Super one important thing you must do is remove every single chat channel that a spy can get into easily, especially public ones, because you can be sure that people will be using this.
