A toady is a sycophant or henchman.
ETA: Yay! Figured out my spoiler issue. You know how blur spoilers toggle on and off each time you click them? If you click it visible, edit the post and then save it, when discourse redraws the edited post it remembers the blur toggle state and shows it visible, as if it weren’t working, instead of resetting to blurred like I would expect on a redraw.
Not a fan, but at least now I know how it works.
