Looks like the Wii U situation is repeating itself. Cheaters have begun appearing in Splatoon 2 and there have been multiple reports of people modyding the weapons parameters and basically becoming invincible.
Is Nintendo going to actually do something this time? And before somebody mentions the recent bans, only two people in total have been banned and theta because they were part of the team who researched Switch homebrew and naturally experimented with requests to Nintendo servers, not a single normal user of homebrew / CFW has been banned.
