As hilariously as the comment is worded - it's honestly the truth and the fact that this blog post is focused on "creating conversations longer than 30 seconds" and not on reducing conversations quicker than 5 seconds (because that's obviously a dong I'm looking at) feels to me like they've really missed the mark.

As uh, depressing as this may sound to the AI that needs to learn it, a hotdog focused neural network (let's just assume we'd call it "DongMind" because obviously we would) would probably greatly increase Chatroulette's value proposition.

Why not combine the "hotdog" filter with the collaborative filtering to make much better predictions about mutual engagement by specific users?
