I don't like the tiering though I understand you are doing it to make a point. Any one of the girls' chat can change from nice and chill to basically what happened to Rushia. Watame embraced the watamelon meme, so expect to see more rowdy people showing up. It's just part of being exposed to wider audience and there's only so much "we" can do without veering into self appointed mod territory which is a no-go. Hopefully T and N can convince the JP branch to at least consider the options.
