Through the social networking Web sites can eliminate distrust in people?

it can but not much there is still scammer outside

In general no. Not as long as scams and questionable programs are promoted and allowed to advertise. However you can build trust in your website through your own efforts.

I believe that trust is based more on our desire to get something than objective reality. The more we want something more than the ones we wish we promise satisfaction.

If you use common sense and have the their interest in mind then you can eliminate mistrust.

I think we can eliminate mistrust.
