What type of poster do you hate the most?

Mine are:<br><br><br>Antisemites (I fucking hate them so much, stops being fun when half their fucking pages are filled with antisemitism)<br><br>Furries (also really fucking disgusting for me personally)<br><br>Anti-American type of people (also really fucking annoying)<br><br>People who post spoilers (of shows, books, games etc.)<br><br><br>What do you guys think?
