While I agree that spelling mistakes are painful to bear, I believe you are being too harsh on the author. As someone said on Quora [1]:

"Sarcasm is most appropriate when shared between two people who have similar thought patterns. That's when sarcasm is actually funny. When the sarcasm isn't shared, it's usually an avenue of passive aggression."
