>>5138/pol/ is becoming more and more exclusionary in favor of moderation and moving away from dank memes towards being 100% serious 100% of the time.
Simply put, /pol/ and /v/ have always had similar numbers, but now people from /pol/ would rather browse
>>>/christian/ or
>>>/k/ where they can have a mix of serious discussion and funposting.
Combined with some folks moving over to polpol or other boards, and you naturally see a drop in ranking. If the moseration keeps it up, we might drop more if an alternative becomes available (maybe something like a "pol memes and shitposting" board).
