Looking through the recent activities, it seems there are at least three accounts like this. I assume they're all connected to one person. Either they're a troll or they have some real life problems and wanted to vent it out.
No. It'a not vital at all, especially because I've seen the game and I am 100% positive that Kasumi ia not like that. You can try to do it again, and I'll always revert it. It's already late in my place, so I'll sleep for now. But tomorrow, if I see you make that kind of edit again, I'll revert it again.
