Once when I first started playing WoW I ended up with a really pushy beggar trying to get money off of me. I don't have the mail he sent me anymore, should have made some permanent copies but meh. He whispered me asking if i could spare him some fairly small amount of money, something to the tune of 5 gold.
I messaged back 'no, go quest or farm like everyone else.' I should have just flagged ignore right then and there. The next day when I logged back in I had 15 or 16 mails from this doofus saying that I was a complete bastard, how could I not help out a person in need, etc. I do remember the last one he sent me, though. It went something like:
YOU AHSOLE just gvie me teh money and ill laeve you along
So I went through and replied to each one with the same response: Congrats! You've been reported for being a dumbass!
