Techdirt found this ridiculous article from Fox News fear mongering the dangers of being murdered when you meet up in real life with people you know only from online games. As Techdirt points out, the article is so ridiculous that it borders on satire.
It should be common sense to anybody with access to the Internet that people may not be who they seem. This is especially true of people in online games that are playing roles or characters. Adults especially, have no excuse. Fox came up with 4 examples. There are 30 million people playing massively multi-player role playing games. That seems like pretty good odds to me. In fact, a source in the article references 20 weddings that resulted from people that met in online games. It sounds like your odds of getting lucky are better than your odds of being murdered!
