I find it hard to believe that was due soley to his real name being made available via a forum. If someone can apparently go to the lenghts of trashing someones credit and aiding in their being fired from a job, don't you think they could fairly easily find their real name if they really wanted to as well?
Still, I understand the concern, I just think it's somewhat reactionary. I've been online using my real name since 1992 and I've never once had a problem with my credit scores, job applications, being hired or fired, being stalked, or with confrontations with folks online (of which there have been many). If things like these happen there are many resources for people to use to protect themselves. The law and law enforcement are very well versed in internet crimes these days and generally work to fully assist people having problems online.
