      Lemmy chops off most of the unchanged kbin link: https://kbin.social/m/meta@lemm.ee/t/458933/How-do-I-block-all-of-Hexbear-from-All/top

      So the @ has to be percent-encoded for Lemmy to not try to change it. A bunch of other characters were also unnecessarily percent-encoded, I changed those back to normal now.
