The easiest route is do something similar to Dark Wraith/Retsu: Use your powers subtly and report them to someone who'd deal with it. Like say, the Sweepers. That would be the easiest way: Join the Sweepers and serve as one of the Erasers. Your job would be to find "Outlaws" who are either trolls or hackers, then you reveal their identify to certain Cleaners (A different branch that actually goes out and does wetwork like Asahi) and they'll deal with them.
