I am inclined to think there are more 'woozies' on the free sites. Someone who has paid has demonstrated they are serious about the process and, I believe, are then more likely to be sincere about themselves. That is not to say that 'woozies' don't exist but it is my feeling that free sites are more predatory. Also, the more personal information a site requires of you the more likely you are then to find a closer match. My suggestion is to investigate sites and stick with those that require a membership fee and have a comprehensive questionnaire.
