It started with a meme thread being spammed: "Why doesn't Batman just kill the joker?".
Over and over and over. Kind of like Goku v Superman or Calarts threads, it was real dire spam.
And every conversation always went like "well I get it, Batman doesn't KILL, this doesn't mean he couldn't incapacitate the joker, put him in a wheelchair forever, torture him, mutilate him, or do something else. The rule is just no-KILL".
And other anons mocking saying "yeah Batman should torture him and gouge his eyes out, it's just no-kill right?" "Yeah he technically could rape him too!"
Mocking threads appeared with "Why doesn't Batman just RAPE the joker?" And the replies couldn't mention the no-kill rule anymore because it became a different topic. Therefore, flawless logic dictated that Batman could, in fact, Rape the Joker. And Commissioner Gordon images appeared, and he started pushing "Batman, I know you can't kill him, just pound his ass very hard, you need to rape him Batman!"
