What is the ruling on using pirated games and software due to ignorance of the ruling? Is repentance sufficient, or is a compensatory value obligatory after becoming aware of the ruling? And what is the ruling on assisting in the placement of such programs without using them?

Using pirated software is absolutely not permissible. If your previous use was for personal benefit without monetary gain, then refraining from it is sufficient, as long as you were unaware of the impermissibility of its use. Otherwise, you are obligated to guarantee the lost benefit and any harm incurred by the owners. However, connecting a computer to someone who uses pirated software is not prohibited, and the responsibility lies solely with the person who infringes upon the software.
