You account info was probably phished. You need to change your pw, or be careful of signing into that site. Fb is a scary website imo, many opportunities to get virus's malware. Also I don't trust Mark Zutherburg with all my private info, and who knows who these third party affiliates are that ask for access to you info.

I do use fb, I have friends in other parts of the country that I like to keep in contact with and it's also a source of alternative news and media, but I like to be very cautious about what I do on that site.
