Practice Post

How safe is to give your personal information on websites such as facebook, my space and any others? What´s the limit fot you?

I dont use much facebook or social networks with account personal, I generally use account secondary or old account, and I dont send personal information, for example, my home address or home phone, because is dangerous for my grandmother, one day they tried to do the "cuento del tio". that´s why I limit myself to comment on a publication or post a picture occasionaly.
