I saw the Zoosk advertisements everywhere so I figured I'd give them a shot.
The only good thing to say of them is they have a brilliant ad department.
It doesn't take long before you realize what they're after. Your money. I signed up for a 3 month stint with the website. First you pay the subscription fee, AND a one time "activation fee." The activation fee is most likely to squeeze as much initial money out of you because they know after you try their service once, you will look elsewhere in the future.
This is due in part to the fact that the number of women on zoosk does not increase regularly. You will see the same profiles week after week before anyone "new" pops up. And there is about a 75% chance that "new" woman will be a fake user created by a scam artist.
After only my first month I was uploading any remotely attractive women's profile picture(s) to google images just to see what "popped up." Amateur porn stars, random website images, and photos stolen from myspace pages was what I got. I repeatedly reported these profiles to Zoosk, but their cracker-jack team of admins and moderators didn't seem to mind. I had accumulated 3 pages of blocked (fake) users and I would still come across a profile I'd reported multiple times in the past in my searches. They ban you for putting your email address in your profile, but post a cropped image of an attractive pornstar and they don't fact check in the slightest.
Another thing is the Zoosk Scientific match, and Carousel. Which is where the micro-transactions come in.
Zoosk will regularly send you emails about a "scientific match" which just means, "You're Christian? SHE'S Christian! You smoke? SHE smokes! You guys should totally hook up!" If you agree to the match and she does too, she becomes your "Mutual Match" which must be unlocked with "Zoosk coins" a fake currency that you have to pay real money for, or sign up for spam, surveys, and other garbage to obtain. Carousel works the same way.
So after all this bs you're left much poorer with scarcely a lady in sight. With terrible moderation, horrid pricing, and fake users galore stay away from these rip-off experts. Just do Plenty of Fish. There may be fake users, and scam artists on that site too, but at least I can get the same "benefits" of Zoosk minus the price of admission.
