Basically what I mean by this is that archiving is playing it safe, while just deleting it is more efficient. I'm 100% for removing the shitposting channel as long as we don't have our brony/furry/other fetish children bleeding their discussions into other chats. I don't specifically hate people who have fetishes (feet, furries, bronies, etc.), but I have some moral gripes with people who are interested in shit like actually fucking animals or children. There is a *huge* gray area when it comes to determining whether or not something/someone is too young in a pornographic picture, which then leads to incredibly long and pointless arguments.
In my honest opinion, I don't think we're half as mature as we should be when it comes to allowing NSFW channels. If people can't accept that their porn is against TOS / not favored among the rest of the populace, then we shouldn't have an NSFW channel in the first place. Just having this thread posted sparked an incredibly long argument that should not have to be discussed, thus proving that we're nowhere near where we should be on maturity regarding the subject. Now, I'm not saying those involved in the argument are immature, but rather it just shouldn't have happened at all. Evidence and claims were provided for at least one argument, which is pretty good for a gaming community.
tl;dr - Arguing over what is or what isn't against TOS is stupid. If something is constantly causing problems and breaking the rules of our platform, it should be extinguished, no questions asked.
