I've never really noticed any significant difference in the hogpit and outside of it, and don't tend to notice where the threads are. Tbh to me the tone is the same, and the only difference is whether a thread is talking about something people feel strongly about or not.
Like any criticisms are going to become personal because of the nature of our hobby. All of us are creators, whether it's RP or games or code or whatever. And most people don't take criticisms of their creations or behavior so great, so pretty much any negative commentary about anything is going to swerve to the personal unless someone takes unbelievable pains to be gentle.
A lot of the advertisement threads follow this formula:
"Hi check out our game." "I tried it but the people there suck." "No maybe you suck." "No u"
And people wanna post their random flyby criticisms and throw shade without it ever being thrown at them so I dunno how you do that and make a healthy environment that allows people to talk about flaws in games or people without it becoming personal.
