According to this blog post research has shown that people talking on IM treated users they considered to be geographically far away in a way different to those considered geographically near by: they trusted them less, were less likely to be persuaded by them, and were more likely to give deceptive portrayals of themselves.

So maybe we’re doing the wrong thing. Maybe the way to reduce trolling is not to display real locations, but to fake them – increasing the number of users who appear to be from the same town as you, in the hope that you’d take more care in your own backyard.

On the Internet, no one knows you’re a dog. But it’s obvious you are when you’re seen at the local grocer’s.
