While I agree that Discord's staff being pretty much purely furry and being massive apologists with this sort of stuff, while being aggressive with punishments on anti-furry stuff (see: QuackityHQ being banned due to a biased furry staff) is stupid as forget, Discord as a platform is still loving amazing and I hope it doesn't die. As a VoIP and chat program, along with screen sharing in private chats, and being lightweight as stuff compared to Skype, it's great.
Also the only way furry cub artwork would be illegal would be if it was considered bestiality, since it doesn't depict a human, it wouldn't fall under human-based laws
