Some years ago i tried to get Tinder to work on my phone. I needed a facebook account for it. No problem. I had several. I created new accoutns each time I logged into facebook for some reason. Tinder still refused to work. Somebody suggested that my facebook account needs at least 50 friends. I found groups in facebook created specifically for the reason of gaining frieds. The next day I had 50+ friends on facebook. This account was locked later by facebook (too many random friends :-P ). I got Tinder to work years later after they dropped facebook account requirenment.
