This is not the first time it's happened (In fact I'm wondering if it's the same story just being submitted again 1 year later).
The very real problem is that people in the real world suffer psychological problems, their instabilities aren't necessarily seen by friends and family, they might not of sought counselling over there problems or looking for a way of dealing with depression.
Those people might lead closed lifestyles where their real life friends can be counted on just one hand leading to loneliness and lessening the chances of their psychology ever being discovered.
One thing that usually stops people from committing suicide is self-reasoning, if they commit suicide what did they amount in this world? what did they leave behind? What of the suffering of their families and friends for a loss that they never truly understood the reasons for and it's obvious in loss that friends and family would want to know about their friend or loved one having the problem so they can help (in most cases).
There are people out there that lack compassion, usually immature teenagers and they are the sort of audience that would egg on a suicide online.
However you could put forwards that this doesn't necessarily mean that the internet should be regulated tighter, I mean it's not different than banning people from going into any high building just in case "They are inclined to jump" or ignoring people so they suicide alone with no chance of anyone talking them around, or suicide because the voices in their head told them to do so.
I mean in the example story there is no comment made about the number of individuals that tried to talk the person down, I doubt it was all one way. It would make more sense for websites to have a "Helpful page" for dealing with Support of those that are victimised, suffer depression or suicidal thoughts.
Obviously this is dually noted for future development discussion for this forum.
