Why would being an oldfag on Kiwifarms be a good thing? That would mean you not only experienced and accepted Josh's bullshit, but also potentially dealt with it yourself.
The purpose is to laugh at lolcows. This whole "oldfag newfag" bullshit is detracting from that purpose and setting up gatekeeping. Literally the only things KF "oldfags" actually have over newer members is witnessing meta drama firsthand and being more knowledgeable about cows. Take away the Josh, mod, and user sperging, and what remains is a lolcow archive and forum, which is what it should be.
