everyone is a pp farmer to some extent by such definition, but if that's the case, then why would we have a term for something that everyone, with no exception, does? if that is the norm, then there is no negative connotation to it, but if everyone is not a pp farmer, then there might be some meaning to the term. a human that can walk has no special appeal or meaning if we all can walk, and likewise pp farming is not bad or good, rather it's literally just a redundant term, if we all pp farm.
but i will say that there are certain people who are lower ranked than they should be and some that are higher ranked than they should be, and in those cases we could probably say some have pp farmed. anyone in the top 10 or 100 pretty much deserves to be there, and if that's the case, i would not say they have truly pp farmed unless they are clearly worse than their rank says.
therefore, 2+2=5 QED
