DeviantHEART was an April Fools' joke on deviantART on April 1st, 2013. It was a program that was launched to match up single deviants, like most online dating sites. Some deviants were featured as "Testimonials", who was `Gwendolyn12 and $namenotrequired also *KingdomWisdom and *BrightestDays. It was confirmed to be an April Fools Day joke, and if you hover over it, it would say it's an April Fools Joke.
