You can often find out a lot about people via the web, that may provide insight into their honesty or lack thereof. I would Google the person’s screen-name, real name, and email address. I would also see if the person has a page at Facebook, Linkedin, etc. Also, a search of the person’s name (and location, if it is a common name) at Intelius.com may disclose useful information.
