Relax a bit. Truthfully I suspect CCP is out of line here.
My immediate thoughts are that the player expressing the sucidal thoughts was being a drama queen and annoying people, perhaps even trying to use those tendencies as a way of begging ISK /ships/etc... off of people. There are a few people who play the whole "emo" card for this reason in every MMO and some become quite infamous on their servers, with one server I'm guessing this guy became famous enough to get the attention of the (un)official reps.
To really fairly judge this we'd have to see the content of the letter, and know more about the player in question and what communications he/she has had to get attention on this level to look for a pattern.
In other words the basic intent here is to shut someone up who is looking to get attention, basically telling them after weeks, months, years or however long it's been to either hurry up and kill themselves or shut up about it and stop spamming or begging for in-game resources as a cheer up, or whatever the frak is going on.
Sorry if this sounds cold, but I've seen similar things in MMOs, and not everyone who sounds suicidal actually is, and anyone who plays that game, especially in the long term to become infamous at it, is going to have picked up the right "signs" to drop into the message.
Claiming to be suicidal or "fragile" in some way is not a get out of jail free card for any behavior, and that's what it's sometimes used as, ditto for inspiring sympathy and begging (which is a big deal in EVE Online).
I could be wrong, but I wouldn't jump to conclusions, and honestly I think CCP should have investigated the matter more before commenting. CSM council members exist to do things in the community that CCP generally can't, including helping to observe and "regulate" player behavior and trends therein. Deciding to effectively cut the attention being given to an infamous game-wide drama magnet is actually the kind of reason it exists (whether you believe it should exist or not).
