I created a zoosk account without a photo of my me, it was trees. I did not pay for the service yet because I wanted to look around. Within 3 days I had received 11 emails from prospective women. You can't read the emails unless you pay for the service. As a long time member of many of many date sites 11 emails without a photo is well beyond normal, for a man. For woman this is normal but online dating statistics would show that only 5% of men receive 5.5 first contact emails per week. I can only suspect that they use false profiles and emails or try and get you to join. The only other option I can conclude is that Women must really like trees and are prone to email them more often.
