The game might have been falsely reported again. We'll have to wait and see if Mofu-san is able to restore it again and lift the suspension.
They were, but they had a dispute and now Lipstor has been trying to get revenge by getting the game pulled due to arguing that Mofu has stolen their characters (they didn't steal anything). 16may61 is possibly an alt account of Lipstor trying to pass off as another person who's been harassing Mofu-san on PixivFanbox, as well as this site, for most of this year. Their account got suspended on both sites due to harassment.
