While I love the idea of a LGBT room, I don't think it would work. There is really no way it could be public, it would be troll central. Even if mods were harsh on modding it, it would get to the point it would be near impossible to have a conversation without getting distracted by the constant trolls. Even as a private/hidden room there would still be a ton of issues with trolls, as you would want it to be a room that is known about and open to all, and trolls would take advantage of that. And while most of us would be able to brush off anything a troll said, there are some people who would be there for the intended purpose of the room who would be really bothered by what a troll would say. I know someone started a groupchat a while ago but it died out. While I think a LGBT room is good in theory, I just severely doubt it working in practice.
