While DIGG may be safe, links on it may take you to scam, virus, and phishing sites. For example: http://digg.com/u1SA5a?&id=<redacted> takes you to a very dangerous site!
Be careful -- linked to a "job scam". While I suspect the domain is OK, this link digg.com/u1WmkQ is being used to redirect a fake news site that advertized a "work at home" scam. "
No Positive or Negative rating for this site. Reasons are:
Site does not monitor any links given on this site which opens it as a malware advertisement and distribution center. However, can be used as a good site as well.
