I've purposefully stayed quiet on this until now as I really didn't know Rev, but I've seen this kind of behavior many, many times going as far back as my time on BBS/Telnet (before there was an Internet).  Its always sad to see, but in truth, its inevitable in this anonymous environment.
I just want to point out however, as a former EMT and Suicide Counselor, that you are quite wrong on this point. There are Many ways of crying out for help, and I would estimate less than 10% of them are actually anything to close to actually admitting "help me".  In fact, in most cases, the person doesn't even realize they are crying out for help with their actions, with the cry for help being more of a subconscious survival instinct. According to the American Foundation for Suicide Prevention, 75% of all people who try to kill themselves give prior warning of their intentions.
A small sample list of typical signs of severe depression and suicidal tendencies include:
- Talking About Dying -- any mention of dying, disappearing, jumping, shooting oneself, or other types of self harm; as well as hypochondriasis
- Recent Loss such as through death, divorce, loss of job , money, status,  loss of interest in friends, hobbies, activities previously enjoyed
- Changes in Personality, Behavior and Judgment
- Change in Sleep Patterns, Eating Habits, Sexual Interest
- Fear of losing control -- going crazy, harming self or others
- Low self esteem -- feeling worthless, shame, overwhelming guilt, self-hatred, "everyone would be better off without me"
- No hope for the future -- believing things will never get better; that nothing will ever change
Also keep in mind that these behaviors can begin years before the "condition" reaches a critical point. In fact, many people in this country live with varying levels of mild to severe depression for most of their lives. Just because this pattern of behavior started months or years ago, doesn't mean the person in question hasn't been on a downward spiral. 
The person in question may also suffer from a mild (or growing) form of Munchausen Syndrome.
Again, I'm not saying the person in question should be excused for their actions, nor am I condoning the actions. All I am saying is that the person in question is most likely in need of some professional help, and nothing is so simple and cut and dry as saying that someone in need of help would simply say "help me".
Just my $0.02 worth.
