Though this one could be self-jynxing - for all the stories of 'personal' backstabbing I have heard, so far, it has never happened, which has lead me to question what exactly inspires it beside a sense of solely "lol EVE". As has already pointed out, trust is a commodity. It is not a nonexistent unicorn constructed by carebears.
If it does happen - oh well, it's EVE. You knew it would eventually. Cuddle your internet feeling and get over it, usually by fucking off and playing something else for a bit. The skill queue goes on without you.
Never share personal, RL data of any personal depth. Though too late for me and I do not regret it, it should not be done. Because lol EVE people do exist and will use it to manipulate your kindness or humanity in sn attempt to to validate themselves or raise their importance to themselves and your shared peers. Cause "we all love eachother"or not in public, someone is sitting there right now thinking I am so much fucking cooler than you, and telling people all about it - behind your back, right now.
The best balance for a roleplayer is having a non-RP corp. It is refreshing to hear as a response to the insanity of your week "Well, I don't really get it, but ok... Wanna fleet up?"
