I perceive the forums like this. It's a basement where people gather around to chill and talk about their favorite subjects. While some would have something thoughtful to add to the conversation, there would always be one or two who are cracking jokes and making sly remarks on what other people are talking about. BUT THAT'S OKAY
really because their presence liven up the atmosphere and they usually make the topic more interesting even if they might be high. As for the uninvited creep who has nothing better to say but never shuts up, he's okay too because the rest can just kick him out whenever.
