2) How long do you think it takes for legal battles to process? Jiho will probably have to openly pull strings to get Dani’s case to proceed and will Dani want that? And as I mentioned, it is still a petty crime. Cybercrime unit doesn’t handle that. Can’t even sue for identity theft because the name is implied, not explicit. Anything actually involve authorities is a long arduous process. These events probably happen within a short time despite the seemingly long arc. If she made it into a big deal, they could fear her while also hated her. As I mentioned w real-life case, girl got dogpiled even more for getting the police involved.
This suggestion sounds as unrealistic as the whole hacking but at least the idea of hacking sounds fun and campy. The idea of dealing with paperwork is not.
3) Anyway, your last suggestion is practically just for show and it sounds ok but they need to investigate the real culprit themselves anyway since placing a bounty will only send others to a wild goose chase. Not to mention, it’s still a high-achieving school. Kids don’t just use their extra study time to go on a search for a girl they don’t like or know about in the first place.
Your tactic of getting people on your side also includes making people latch onto a new victim. It is very much something that got used in Inso’s Law side story but it only left the user feeling empty and sort of bitter. Not to mention, the target was not a slippery eel like Choi Yuri lol.
