Is this a scam or some sort of dangerous site?

Well someone asked a question here on Yahoo Answers and it involved a link to what was supposed to be a Facebook page. The page was not from the Official Facebook though, some weird version that looked like a copy.

What worries me was that the link they posted looked like it was going to direct me to the real Facebook but instead took me to the fake. I want to know if it is any threat to my comp or just a fake site.

The site url was called: fb-lt.facebook.com
I can also post a link to the person's question if you would like?

Most probably it must be a scam site only. Anyway, You can visit www.WhoisXY.com have a whois lookup and ensure whether it has been registered with Facebook inc., If not it is sure it is a scam site. There are many such scam sites to hack Facebook profiles. Be cautious.
