Actually, i wouldnt agree on the example of:

try imagining some new forumer comes in, with 0 post count, flaming some old skool forumer that has 3004002 post counts (provided they are legit non-spammed posts), in a 3rd person's view, most likely you're going to take the one with the most post count when it comes to post credibility. of course, this is always subjected to the thread topic/contents, the posts being posted by both sides, and of course the contents of the flame posts. But you get the idea that YES, it CAN actually give a benchmark on one's credibility, so indirectly yes, said poster with 3004002 post would prolly have a package thats longer, thicker, and squirts further.
