Instagram Direct allows you to send photos and videos privately. It is a private messaging service that is used to send a photo or video to another user. You can send photos and videos to any Instagram user (a follower, friend or any other user) via Instagram Direct as a private message. It allows you to share private photos and videos directly with individuals or groups of up to 15 users. The photo or video will go to the recipient's inbox if they follow you. If you get a direct message from one of other users you are not following, then the message will go into a requested folder. You can decide whether or not to allows it or not. Click the green mark to see the photo or video. If you don't like, you can choose to ignore all future direct messages from that user.
