If someone has watched pirated movies and shows and played pirated games in the past, but has now repented, does he have to pay for the pirated content?
Bismihi ta'ala
Although using what is referred to as "pirated" maybe illegal in some countries, due to violation of copyright laws, it does not necessarily mean it is haram to do, from a shar'i perspective.
This would mean that there is no need for you to "repent" for such a thing. I would advice one observes caution, so as to not get legally in trouble, and follow the infringement laws of where you live.
And Allah knows best.
