Discussion: Research and Social Media

I’m working on a sociology multi-part question and need the explanation and answer to help me learn.

What would you do if you were interviewing college students who spent lots of time online and found that some were very isolated and depressed or even suicidal, apparently as a result of the isolation? Do  you believe that social researches have an obligation to take action in a situation like this? What if you discovered a similar problem with a child? What guidelines would you suggest for researchers?
