I just needed to send out a survey for a class project, and the only way was to subscribe for a month. They automatically make your account auto-renew. The one survey ended up costing just under $100, as I forgot to unsubscribe. Moreover, that was a basic survey, without much of any analytics at all. There doesn't appear to be a way to unsubscribe from a mobile device, and it is not immediately intuitive from a computer. Once you do, they try to guilt you into staying. Quite a disgusting greedy company in my opinion.
