Shares of Match Group fell 15 percent after the company announced it will miss revenue goals for the fourth quarter. Shares of IAC also fell by 11 percent, according to Reuters.

The company expects fourth quarter revenue to be between $545 and $555 million, short of the $559.3 million goal according to IBES data from Refinitiv.

This news comes on the heels of a complaint filed by the U.S. Federal Trading Commission that Match Group offered fake profiles to entice customers to purchase paid subscriptions to its services, among other “deceptive and unfair practices,” as said in the lawsuit. Match Group is also facing legal entanglements with former Tinder employees, including founder Sean Rad, who said the company cheated him out of rightful payment after undervaluing his stock options.

Facebook Dating just launched, but privacy advocates are warning despite all the opt-in features, Facebook could be collecting more data than you realize.

Facebook Dating is reassuring potential customers by allowing them to make decisions about how visible they want to be on the app – including providing features to block certain users from appearing in your matches (like an ex) and hiding your dating profile from friends and work colleagues. Even some of the more questionable features – like “secret crush” – where you can identify someone you secretly like over the app, and if they do the same you two are matched, are only activated when users choose them.

More than a year after the company first announced the feature, Facebook Dating has finally made its way to the US. Anyone with a Facebook account who is over 18 can opt into the dating service from the Facebook mobile app.

"We've been really slow, actually, with this rollout," Charmaine Hung, a product manager at Facebook Dating, told CNN Business. "We really wanted to make sure we got it right because dating is so personal."

Was Facebook Dating worth the wait? Here’s what you need to know before giving it a try.

Facebook Dating made its much-anticipated debut in the US on September 5th, but concerns about its privacy issues have overshadowed the excitement in media coverage of the app.

Facebook was recently ordered by the Federal Trade Commission to pay about $5 billion in fines for privacy lapses, including its maligned partnership with Cambridge Analytica leading up to the 2016 elections. And most recently, the Attorneys General of eight different states have launched an anti-trust investigation of the company, specifically concerning the company’s privacy practices and purchases of WhatsApp and Instagram.

Still, Facebook Dating is betting on its wealth of personal user data as a competitive advantage for creating better matches to directly compete with apps like Tinder. (Match Group saw its shares fall 5 percent on the day Facebook Dating was launched, a sign of investor concerns about the new competition.)

Phone numbers linked to the Facebook accounts of more than 419 million users have been found online thanks to an insecure server.

According to TechCrunch, the server contained records from multiple databases, including 133 million records on Facebook users in the United States, 18 million records of users in the United Kingdom, and over 50 million records on users in Vietnam. Each record contained a user’s Facebook ID - a unique number associated with every Facebook account, which can easily be used to ascertain the account owner’s name - as well as the phone number listed on the account. Some records also contained the user’s name, gender and location by country.

The server was not protected with a password, allowing anyone to find and access the database. Sanyam Jain, a security researcher from the non-profit organization GDI Foundation, discovered the database and reached out to TechCrunch when he was unable to identify the owner. TechCrunch confirmed the authenticity of a number of records in the database, but was also unable to find the owner.

Got a secret crush on someone in your friend circle? Facebook now has a feature for that. At its annual F8 developer conference, the social networking company unveiled the newest addition to its dating product: Secret Crush.

Secret Crush allows users to select up to nine Facebook friends they want to stealthily express interest in. Each user who is selected will receive a notification saying “A friend added you as a secret crush.” The sender’s name will not be revealed unless the recipient also puts the sender on their Secret Crush list. If a mutual crush occurs, Facebook will make the match and reveal the names. If their feelings are not reciprocated, the secret admirer’s identity will remain a secret.
