I'm talking about things like "The Real Dislike Button!!!!" and "Become a fan to get a quadrillion in-game dollars!!!" The first is an application that one must permit to access one's information and friends list, the second being a scam to get members for whatever reason - they all say one will get whatever prize by becoming a fan and then inviting one's entire friends list - which doesn't even have the potential of working like the user hopes it will.
I am very wary of what the "developers" of these lists and applications are attempting to do (and I use the term "developers" very loosely here) and I want to protect my friends from themselves. I haven't said anything except when one friend started using an application that said "Your Facebook account is in danger of being deleted - please reactivate your account by entering your email and password" - and she did, and then passed it on to all of her friends so we could ensure our accounts were safe. Smelling a rat, I checked the app info, and lo and behold - not developed by Facebook. I told her to immediately change her FB password so as to avoid getting hacked, and to report the app as being a potentially harmful phishing app.
When should I say something, and when should I keep my mouth shut? I think my friends have the right to play Russian roulette with their own information if they choose not to play smart, but when (or how) should I help them become more savvy if they're open to the idea?
