Since you brought up Vlad III, it’s probably worth noting that claims that he “inspired” Bram Stoker’s 1897 novel are grossly exaggerated. The truth is that Stoker had pretty much finished the novel and was just weeks from publishing it—under the title Count Wampyr—when he came across stories of Vlad the Impaler, and decided to change the name and a few minor details to fit.
Karma was also a really handy tool for mods to keep away bots and trolls.
