There should be no way to track if someone is dead in game (apart from either them, or their killer telling people... personally, I think saying "OMG, I just died!" is terrible roleplaying... but meh).
It does look like there's a bug in regards to the 'never logged in', giving everyone that status right now, so don't think too much of it.
I would also ignore Siarica Aylina's suggestion (the other guest on this thread) that "is a good way to track a character and see if he is still existing". Given Siarica was recently permabanned for breaking the rules, he's not the best person to take advice from in things which are a 'good idea'.
As for what appears to be an arguement over posting a question as a guest... there really is no need. It is also pointless as it took me a few seconds to find out who you were, Baz. What you said had no detail as to who you were looking at, any information as to why you were looking into it, but asking the question as a guest did suggest that you were intending to use the information for questionable means, given that you are hiding your identity and argued against people who questioned that.
Unless specifically stated, this post is not the view of the Star Wars Combine Administration and should not be viewed as such.
The ability to post as a Guest within the Question Centre is to allow those who cannot log in, or those who do not yet have an account, to post for assistance. It is not intended for normal members to be allowed to hide from being associated with their own questions. If you can log in, you should log in to post.
It's probably worth adding that to the stickies in these forums.
Also note that the Guest feature is not intended to allow permanently banned players to continue trolling the game.
