One app that we have used and found some good features in is LoveScout (Meetic, Match, Affinity). Unfortunately, they also have one very annoying feature… this is, that when a profile has been deleted by the user or even by the site/app, they leave a placeholder on your Likes and Visits screen and even in your messages system. This takes up space and is completely pointless because once the profile is deleted you are clearly not going to have any further contact.
A solid dating app should remove all traces of deleted profiles from the users’ view. However, they should maintain an internal record for maintenance and future checking if the profile is recreated.
