@hardmath yeah @PetəíŕdtheWizard is correct, there was indeed a spam answer by that user. Another way to know such a thing is clicking the "modified" label:
This would lead to e.g. meta.stackexchange.com/questions/170349/… and while you can't see it without 10k rep, you know it means there was answer that is now deleted.
@PetəíŕdtheWizard That word is already said in the latest 10 words. Please use another. (In case I'm mistaken, run >>rmword va and then >>reply 9993346)
