What I object to is someone who literally has no connection saying "I heard about this and want hugs for me Me ME!"
While I agree that this is rather distasteful, I hesitate to endorse any rules based on that. For one thing, it might come off as "literally no connection" and just a self-centered cry for attention, but maybe it's poorly worded and actually not just that. The event really did stir up strong emotions in the person who posts, whether they are about someone affected that the OP knows personally, or that the suffering of random people just hit the OP in a particularly bad way, or what.
The person for whatever reason wants a "hug" and it's really hard for us others to judge if it's real or not. I really doubt anybody here is posting in the hugs folder just thinking "I'm bored and not getting enough attention, so I'm going to post in the hugs folder about this random tragedy I don't actually care about, so I can see a lot of posts about ME."
And even if somebody does that, well, the rest of us can either respond or not. We can all read each post, judge the sincerity, and reply or not as we see fit. And which direction is it better to err? On the side of supportively responding to someone who just wants attention and isn't really upset at all and doesn't need it? Or the side of ignoring or calling out as a troll the person who really is upset by the thing and doesn't quite know how to articulate it but really does need the support that could be provided by a virtual hug?
On a side note, I personally did not post in the hugs folder about this but I was very profoundly shaken up by the death of Michael Jackson, even though of course I don't know him personally, and quite frankly, I've never been a fan of his music. But I was shaken up and upset for a few days because it reminded me that the world is not the same as when I was a child, that I am much older now. Enough time has passed for someone who it seemed like always had been here and would be here forever, aged enough to now be dead. I became very aware of how detached I was from modern performers, how I knew more about MJ, despite not liking his music, than I knew about many of the current stars of today.
It was a time of much meditation and contemplation about age and the passage of time and the cycling of life, of young people and famous stars, how eventually even this generation that is the youngest now, this will happen to them someday also. And if I had seen a post in the hugs folder around that time, where somebody just said "I am really upset that MJ died" I would not assume it was just a random cry for attention. I would assume their feelings were similar to mine.
Bottom line for me, is that we need to be really careful about judging others, especially in that forum. People post because they want a "hug" and to get some would make them feel at least a little better. And the rest of us are free to give one or not give one.
