Currently, JFBConnect generally does not require Reclaim Account management. This is because, if you set "Create New Users" to "Yes", a Joomla account is created for each of your users. Therefore, even if they abandon/close their Facebook account, they can return to your site and log in with their Joomla credentials.
Unfortunately, if "Create New Users" is set to "No", then your users would not have an account. We can look into possibly integrating features to support "Reclaim Account" in the future if there's enough user requests for it.
