kid-friendly MMOs have systems to guard children from unwelcome contact and identity theft, they still require the assistance of parents to teach their kids how to be safe in games.
The Ancient Gaming Noob's Wilhelm recently shared a cautionary tale involving his daughter, Club Penguin, and a breach of account security. Even though she was cautioned not to share a list of details with anyone in game, all it took was the offer of a special item to get her to give up her account name and password to a stranger. This resulted in a headache, as the account was banned, and Wilhelm went back and forth with Club Penguin to re-establish his daughter's account and security. In the end, he found that Club Penguin's security was just as questionable as his daughter's judgment, and passed this story along to the rest of us in an effort to guard our own young ones from this unfortunate event.
Considering that account security, personal identity and privacy are hot topics these days, we feel that this story is an eye-opener as to how far both game companies and families have to go to protect our loved ones from being exploited.
