We have added like count on each dating profile. It is for both the mini profile (eg on the People search page) and on individual user profile.
Dating profile likes are an important part of our dating website. When you like someone’s profile, the user gets a notification on the web as well as an email notification. The other (liked) user gets the email notification only if they have email notifications allowed in Settings and if they are offline.
There is also cap on how many likes one user can give within a certain period of time. When this limit is reached, the user gets a message and has to wait until he/she can perform dating profile likes again. This is to prevent spam.
