What can your worst enemy find out about you?
IT IS yet to be widely released in Australia but Facebook already is in hot water over the planned unveiling of its "Graph Search".
The new element for the social networking giant allows users to find information through friends, rather than relying on Google.
For example, they might search "Friends in Brisbane who like country music".
A blog website titled "Actual Graph Searches" has now sprung up highlighting its hilarious, bizarre and potentially deadly uses In one of two examples, creator Tom Scott finds "Islamic men interested in men who live in Tehran, Iran".
Homosexuality is illegal in Iran, potentially punishable by flogging or even execution.
With another, he finds "Family members of people who live in China and like (outlawed political activists) Falun Gong".
His searches also found examples of Jewish women who enjoy bacon, companies with the most staff who claim they are racist and potentially unfaithful spouses.
Earlier this week, Australian Federal Police and Queensland Police Service warned of inherent dangers built into graph search.
Queensland Police Fraud and Corporate Crime Group Detective Superintendent Brian Hay told APN a predator could create an alluring or desirable persona by listing experiences or locations, creating a "honey pot" to attract targets.
Mr Scott's blog published another troubling example, easily finding "more than 100 people" when he entered "single women who live nearby and who are interested in men and like getting drunk".
A spokesman for Facebook said any information that popped up on this search was already available through people's privacy settings.
Facebook was also working closely with the Federal Government, he said, to ensure better communication between Facebook, authorities and ensure transparency.
He said there was no indication Facebook would change graph search before it was officially released.
Back to the blog, Mr Scott offered this advice, "If it'd be awkward if it was put on a screen in Times Square, don't put it on Facebook".
"Oh, and check your privacy settings again."
Want to ensure your Facebook is properly private?
Here's how to make sure:
STEP 1: If on a computer, click the tiny cog in the top right.
STEP 2: Click "privacy settings".
STEP 3: Look through your general, security, privacy and timeline settings and ensure you are happy with what you're making public.
If you would not want your worst enemy knowing the information, make it private or friends-only.
Birth date, address, phone number and workplace in particular should be kept vague or invisible.
