You do not have to like pictures on your Instagram app for Like4Like to work.Like4Like is an exchange network for Instagram likes. We do not give or show you the pictures to like as other sites do.
We will automatically exchange likes for you if you have activated the blue switch on your account when logged in:
Once we match you with a picture to like our system will automatically do it for you, and you will be rewarded 1 heart in exchange.
