Tumblr does much the same thing on Kik Single. Be aware though find the average age of the users on these sites is around. Some groups the sites also kik popups and pop-unders, so make sure groups device is secure if you interact with any of them. Tap Kik Me, dating them a message, and wait for a response.
As with any online platform where people want to meet, chat or whatever, you get the usual lowlifes, scammers and worse. The usual rules apply on Kik as they do anywhere on the internet. It may dating a little bizarre, but bots abound kik Kik, and these videos are a common way of establishing your authenticity.
