I have been a paying member of eHarmony a couple of times. They match members with non-paying members who are unable to respond. From eHarmony's Q&A section:

-------------

Question: Are users required to post a photo?

Answer: eHarmony doesn't "force" our users to post their photos, and we wouldn't want to. We have promised to begin matching you as soon as you are accepted into our system, even before you have subscribed. This helps to demonstrate how we work, and is one of our most important methods of generating trust in our service.
-------------------

More like one of their most important methods of generating revenue.

Before you pay, you are unable to see photos of "matches". The text which appears where a photo would be says,

"You must be a subscriber to view photos if posted. "

Be sure to read the last two words: IF POSTED. You are most likely to find no photos are posted even after paying to join. Of course, there is bogus spin about the insignificance of appearance. Here is more of the "answer" from the question about posting photos:

----------
If posting a photograph were a prerequisite to completing the Relationship Questionnaire, this would exclude anyone who didn't have scanning equipment immediately on hand from joining eHarmony, severely limiting our membership. In fact, you may remember that we matched you before you had photos posted, and I'm sure you appreciate that we did not eliminate you from matching before you could amend this situation.
---------

More like severely limiting their revenue! In fact, you were used by them to scam others into joining! At least the sort of acknowledge they are going to use you just like they use everyone else. It has been my experience that the only people who do not post photos are those most others would find unattractive and would not want to meet no matter what. Without these people, eHarmony would likely go out of business.

If you decide to pay for a membership, be prepared for meeting many unattractive people who refuse to post photos before meeting. Be sure to meet for coffee or water so you don't go broke on bad dates.

Matched by eHarmony with man by the name of Frank Larry, Dallas, TX. Pictures posted and later in the process sent. Man identifies himself as being a car dealer, born in Dallas but raised in another country, and returning to Dallas approx 12-18 years ago. A widower, with one 11-year-old son. Pictures forwarded. Provided my home # and the call came from 646-465-7602 (Brooklyn) (icall.com) which is a free service to call anywhere in the USA and Canada from another country. The caller was definitely not American, perhaps South African/Nigerian... did not exchange too many correspondence as after hearing the voice, IMMEDIATELY advised person to stop calling as authorities are tracing call. So far so good. Please be aware! Many scammers out there taking advantage of people, both women and men.

Well, here is my embarrassing story, and please note I am doing my own investigative work, no party is guilty; HOWEVER... Matched with this incredibly awesome man via eHarmony. Says all the right words, attentive, AND supposedly is in the military - a brave soldier currently on active duty in Afghanistan.

Well, my brave soldier since he met me asked me to front over $5100 in USD. Hmmm what is wrong with this picture? No no - different increments. Okay, so I was stupid and began my questioning and researching only AFTER the fact I wire $300 to his "agent."

Well public records do not show my match to exist (Martin Joll/M.Joll of Erie, PA) no matter what state I have been told he has lived (TX, MA). His parents are dead. He is divorced. He is an only child. While I cannot deny any of this to be true, the matter of no public records for a 46 year old who has been married, divorced, purchased homes, etc. is not 'normal.' A recent package sent to my kids by him, lists another man's name, when questioned, it was the name of a fellow trooper, a good friend helping another friend in need, by ordering and paying for the shipment. I placed a call to this company where shipment came from, they can only confirm the sender's name AND that the bill was paid by another name... hmmm did I not mention the sender was also the guy who paid the bill for my awesome liar? I have 2 pics -- but I do not know if this is him or not... I have never seen him. No webcam is allowed in the camp where he is at. I am unable to mail care packages because nothing is allowed to come in and out of he camp....all possibilities considering he very well may be at the front lines in Kabul, but all so very suspicious. No telephones are allowed so I cannot hear his voice - does he have an accent? Ughhh.

I post this ONLY because he is still, to my knowledge, and active subscriber to eHarmony. Even so, from what I am reading eHarmony still forwards inactive subscriptions as matches --- I can definitely confirm this as my subscription has been inactive since July 12 and I am getting matches all the time.

LADIES BEWARE OF M. JOLL, military, Erie, PA!

Now, if after further investigation, my "red flags" are false, then I owe this man a major apology but until then, I remain guarded and hope if anybody out there in cyberspace can provide me additional information, please please contact me and/or post a reply or your situation.

I was encouraged to join eHarmony by a friend who met her husband on eharmony (this was the only person who responded to her many inquiries) and to be honest, I met someone within the first month. He turned out to be a jerk, so I continued to be a member. I responded to at least 100 "matches" and never got a response back. I wasn't closed out though. Now I know that most of these are probably expired members - what a sham! I ended my membership and kept getting matches. I was suspicious as to why my profile was still up but then got a message that someone had taken the first step. Although I knew in my gut something was wrong with this, I let myself get suckered into rejoining. Of course, it was no coincidence that at the same time I received a message from a match, I also received an email from eharmony asking me to join with a much more attractive subscription fee. The "mystery match" appeared to live just a few miles from me and we got to level 3 when the "match" suddenly closed me out and the reason was "I think the physical distance between us is too far." How could this be when he supposedly contacted me first and only lives a few miles away. That's when I realized it was probably a phoney match set up by eharmony to entice me to rejoin. (and of course, there was no picture of the match, confirming for me this was a phoney). I am only sorry I didn't listen to my gut and let myself get suckered in. I'm no fashion model but I am smart, funny, literate and nice looking so there is no reason in four months that I couldn't even get to another level with more than 1 person. I feel like such a fool and am telling this story so others don't fall into the scam of eharmony. I'm not saying that they never make a legitimate match (my friend is proof they do) but I think they are few and far between and they definitely use fraudulent practices to get your money. You have way more chances of meeting someone by just going out and being social. Dr. Warren should be ashamed of himself. Frankly, I have tried other sites as well and they are not much better although eharmony is definitely the worst so far.

Don't waste your time with eHarmony. I only signed up for a trial subscription (thank goodness) and soon found out that the service is over-rated. The service charges over a few hundred bucks for a year's subscription--it's a rip-off. Five to ten dollars a month is all they should be charging. Neil Clark Warren is pocketing a ton of money. Neil claims to be a Christian... I don't think it's godly to be charging such an unfair rate.
