This may seem baseless, but I have seen this from years of experience in online forums. You don’t have to take it seriously, but maybe you can relate. We have seen time and time again that if there is no moderation then the shit floats to the top. The reason being that when people can’t post something creative or fun, but they still want the attention, they will post negative. It’s the loud minority, but it’s a very dedicated loud minority. Let’s say we have 5 people and 4 of them are very creative time and funny, but 1 of them complains all the time. If they make posts to the same community then there is a very good chance that the one negative person will make a lot more posts than the 4 creative types.
