The sexual orientations and personal details of millions of Internet users may have been exposed in an alleged breach of a social networking site aimed at intimate encounters.

But it's just the latest sign that Internet users looking for love online -- or just hoping to hook up -- face privacy and security risks they might not expect.

Beginning with newspaper classified ads, many have hoped to find their ideal love matches by broadcasting their single statuses through popular outlets.

Through the years, the growing popularity of the internet, classified ads have evolved into online dating sites.

A security review company that released a study ranking Buffalo as the most dangerous city in the nation for online dating has revised its numbers after inquiries were made.

The revision improved Buffalo's overall ranking, although it remains in the bottom 25% of cities when it comes to online dating safety.

(Provided) Looking for love online in South Carolina? South Carolina is considered the sixth most dangerous state for online dating.

That’s according to a new report by Safewise, a home security company, and highspeedinternet.com, which helps consumers make decisions about internet service providers.A community outreach strategist for Safe Wise acknowledged several days after the study was released that researchers inadvertently over-counted the city’s rate of sexually-transmitted diseases.“There was a miscount when adding up the STD numbers for Buffalo,” explained Sage Singleton.With millions of members belonging to many sites, it seems everyone knows or is one of those users.This is the type of scenario members dream of when signing up for a dating site, but they are not entirely common or guaranteed.Even being revealed as a member of Adult Friend Finder might be embarrassment enough for some: The site is, as its name suggests, "adult" in nature. Penthouse Media Group acquired it along with the rest of its network, which also includes less risque sites aimed at religious and senior daters among others, back in 2007.
