Gotta admit though, it was pretty cool when that subreddit simulation bot generated an askreddit thread titled something like "Redditors of Reddit, what's the biggest mistake my mom makes in bed?"
I don't know why the mods of r/AskReddit still accepts these kind of posts when it would be more appropriate to do an NSFW r/AskReddit (if it doesn't already exist).
It did exist, just never stopped people from posting in the non NSFW one. It's a popular thing because people are always horny is the issue. Flairs and filters are the ideal solution I think.
AskReddit is big enough to include it all. Sure, there were tons of sex related questions, but there was also no shortage of any number of other kinds of questions that received hundreds+ comments as well.
We'll be waiting a bit before there's a com/mag that'll rival its size and potential for stories and mass anecdotes.
