Newsflash: The internet might not contain 100% honesty.

Courtesy of Newsweek:

"[MySpace] has got to take this seriously." Attorney Carl Barry, who is representing a 14-year-old girl and her mother in their $30 million lawsuit against MySpace.com. The girl was allegedly assaulted by a 19-year-old man who contacted her through the networking site.

What? No they don't! She's suing MySpace because someone used it to be dishonest? What brand of idiocy is this?
A few points:
1. If you read the MySpace TOS, it seems like they've covered themselves fairly well. They say you're not allowed to impersonate other MySpace users, you can't use it for anything illegal, etc. Items 10 and 12 are particularly relevant, I think:

Member Disputes. You are solely responsible for your interactions with other MySpace.com Members. MySpace.com reserves the right, but has no obligation, to monitor disputes between you and other Members.
...
Disclaimers. MySpace.com is not responsible for any incorrect or inaccurate Content posted on the MySpace Website or in connection with the MySpace Services, whether caused by Users of the MySpace Services or by any of the equipment or programming associated with or utilized in the MySpace Services....

Meaning: if you are legally using our service you are by definition 14 years of age or older, and therefore, old enough to not be a helpless idiot. Take responsibility for yourself. If some random person online says that they're your age and want to meet you, this does not mean you should trust them.

The era of taking responsibility for your own actions seems to be gone...
