Eharmony is making alot of money in the lonliness business and what is worse they KEEP your profile active after you terminate the service . They also abuse your credit card and renew it without your permission. I fully believe they will be the brunt of a class action law suit at some point very soon. Now on to the basics they match you up using some random formula I have maybe one or two attractive women out of like 1400 matches and what makes it even more ludicrous is that most of the forced matches do not even have photos on the profile.
It is very sad that such a service can bill itself as some reputable when there are others out there such as Match that are much better and even some free ones like Plenty of Fish and Tagged that get better results.
