It is actually designed to be addictive for profit, much like other addictive things. If you are exposed to Zina of the eyes, seeing pictures or videos of immodest people while using a website, then it is Haram and it is best not to use that website. That can actually subconsciously cause your addiction and be the reason why so much time in your life is going down the drain.
Many times, people will be disappointed to learn that something is Haram. Think about this. You could be eating an entire cake every day for breakfast, because you want to and you like to eat cake, but it will actually make you feel very sick and also you long-term health problems. This is what Haram is like.
Whenever you take out a Haram from your life, Allah will replace it with something better. For example, if you overcome social media addiction, suddenly you have reclaimed all this time in your life for something better. For family, for study, a special interest, a new opportunity in life. You will have an advantage in life if you avoid Haram, because sin causes a lot of problems and eats away life. Small vices kill big dreams.
