Logojoy assumes that your need for a logo will outweigh the artificial roadblock that they place in the workflow. The only problem is that they've provided no carrots leading up to the roadblock, so I have no motivation to continue. I need to test the service and have confidence in its quality before I sign up for anything. Never mind that I don't actually need a logo, I'm just curating a resource for future use. So I have no innate momentum besides mild curiosity, and I bounced.
