I'd have to go with what the original post said about new members joining and sharing their opinion then being instantly bashed and neg repped. Which leads me to another thing - reputation. A lot of forums have a very broken reputation system where people can be repfucked or neg repped because they didn't agree with someone, and they are usually judged based on reputation. Then again, it also shows the users that are trusted and respected. I also dislike when people post random things just for post count. Stuff that doesn't necessarily relate to the OP. I could probably go on and on, but those are some of the main things.
