I read the facebook chapter in HTBI3, which pertains mainly to youngsters. My question is whether measures can be taken to safely set up and use such sites. For example, use an alias that you only give out to those you trust. Maybe use your real first name (if it's common enough) but falsify the last name and other registration requirements. Don't post pictures and choose a secure password.
Isn't there anyway to have the benefits of social media while avoiding most of the pitfalls?
