Goodgrief has no “like” feature as it is not an ordinary dating website. The users come here to talk and without looking for love or romance with each other (even if it is not excluded in some cases). Moreover, there is no feature to see who has visited your profile.
There is a tray of recommended users in the lower part of the page. You can scroll it to find an interlocutor without using the main filter tool. You don’t need to pay for the service for two first weeks. However, once your trial is expired, you have two options – to pay and stay or to leave.
