Hi C..
It's possible that MySpace & Yahoo could be dangerous. In my opinion there is few types of risk and few basic rules:
- Never provide certain types of information: SSN, phone number, address, and information such as that.
- Never click on links provided from strangers, in some cases you can also receive bad links from friend if it PC is infected with some types of worms etc.
- Always take care what kids do on social sites because of: unsuitable written content & images, Predators (pedophiles), unsuitable friends...
That's all what I now have on my mind...
Hope this is helpful for you?
Regards,
Samker
