Its free to wink a profil to let them know you're interesting, and you have an answer saying that they are interesting, so you write them, cost you 8 credits, to find out that they never write to you again... Its generate by the site itself
Also, the "Priority Message" is automaticly set ON. If you don't turn it OFF, you first message cost you 8 credit + 5 credit for priority. Then all other message to that person are free, but if you forget tu set Priority Message to OFF, it will cost you 5 credits each time.
I spent 200 credits and I THINK I spoke to 1 real girl... All other girls stoped writing me soon I accept to send them a message for 8 credits, so waste of money site
