I like when it insists I'm using escape characters in my text when I absolutely am not and I have to convince a machine I didn't type a certain string of characters because on its end those are absolutely the characters it recieved.

The other day I argued with a bot for 10 minutes that I used a right caret and not the html escape sequence that results in a right caret. Then I realized I was arguing with a bot, went outside for a bit, and finished my project without the slot machine.
