Kik Messenger is an interactive messenger that is unlimited and free. It is not at all similar to Facebook or Twitter, it is not an online social network and you choose who you want to add. Also, there is a blocking feature sutiable to block anyone who is causing the user problems, also Kik are very strict and any unacceptable behaviour can be reported to Kik. Kik website provides information about Kik and phones avaliable to download Kik on, it is not a place to access Kik. Kik can only be used on a smartphone (depending if Kik is avaliable to download from the smartphone's application store). On Kik, your details do not appear. You can create a nickname, and you don't have to upload a picture of yourself. Nonetheless, Kik is not to everyone's liking but it is worth trying Kik out.
There is so caution to be taken, Kik offers related apps and one called OinkText will send alarm bells ringing, it allows Kik users to chat with total strangers, OinkText does not come with Kik, it has to be downloaded seperately to use, it can be unsafe as unknown people may cause trouble to other users.
