You know how averages work, right?
Honestly, someone who posts everyday averaging 12 comments is probably crazier than the occasional poster who very occasionally hits 50 200 in a day.
Edit: I misread the limits as being 50 comments, which I stand by as not too crazy now and again. 200 comments/replies even on the most newsworthy days is certainly getting to the ‘difficult to do’ level. I’ll grant you that I’d be hard pressed to get to 200 even if I tried. I consider myself on your side on this one. I’ll only say that citing any average usage per day is unimportant, because there are no limits on the average daily usage, only absolute upper limits.
