This site is dreadful. It's full of fake profiles and, I believe, site-controlled accounts that email out irrelevant messages. The search parameters don't allow you to filter by last log-in and the profiles don't show when they last logged-in. I cannot believe there are hundreds of women looking for a man within 1 mile of my postcode.
As others have said, they link several sites together so you find totally unsuitable matches. In all, do NOT sign up and definitely do not give them any money - they automatically recharge you.
