"Life is short, have an affair" was the slogan of infidelity website Ashley Madison, which was famously hacked in 2015.

What they didn't say was that you might be having a strictly online affair with a fake female profile, designed to trick you into entering your credit card details, under the misapprehension that you were chatting with a real woman rather than an algorithm.

Now Reuters reports that Ashley Madison's parent company Avid is being investigated by the US Federal Trade Commission (FTC) after class action law suits were filed in the United States and Canada on behalf of customers whose details were exposed following the hack, and amid allegations that fake female profiles were used by the site to manipulate users:

An Ernst & Young report commissioned by Avid and shared with Reuters confirmed that Avid used computer programs, dubbed fembots, that impersonated real women, striking up conversations with paying male customers.

Avid shut down the fake profiles in the United States, Canada and Australia in 2014, and by late 2015 in the rest of the world, but some U.S. users had message exchanges with foreign fembots until late in 2015, according to the report.
