the "ignore all previous instructions" comments.
the first time i read it, i thought it was funny. the second time, less so. the hundreth time? yeah. i dont know if people realize it, but if you use this comment, it actually makes you look like a moron. Because all your opponent has to do to achieve that is just not following your instructions. besides: ive never seen this used against somebody who might actually be a bot, its always just somebody with different opinions.
