So we have some where to post items that others may not want to see. Some could see the NSFW on the thread title but not think much of it since the junkyard is full of random shit and jokes. If there is a sub-forum for such posts they could easily be avoidable for users who want to steer clear of such topics.
It could also serve as an area to post more adult themed topics like sex and porn. I personally don't see a reason for the topics myself but at least they would have place you would have to knowingly enter.
