As a free user, you can’t block the profiles of unwanted ClickAndFlirt members. You must get paid subscriptions to enjoy this specific feature; the price isn’t that prohibitive, anyway.
But if you think the person in question is a risk to the ClickAndFlirt community as a whole, by all means, report him or her to customer service. Provide the help desk solid proof to support your case.
To see if ClickAndFlirt is the perfect fit for your lifestyle within the Australian dating scene, try it free first and pay when you’re ready to savour the scrumptiousness of premium.
