If theymos wants a 70-80% decrease in forum activity
That happened already, after the introduction of Merit. We're now at
48,000 posts per week, that used to be
280,000 posts per week. It dropped by more than 80%! The crypto bear market might have had something to do with that too, but even in last year's bull markt I think the maximum I've seen was still less than 80,000 posts per week.
