I'm genuinely curious as to why you think the bot would be posting "faster" to someone's opinion or statement than a person who can read the statement and respond as fast as they can type..

I can see people setting up some form of pre-loaded opinion/responses based on what they want to be seen as..e.g. if $OPINION_I_DISLIKE print $YOU_BAD else print $YOURE_RIGHT! but that seems like it's pretty limited as to completely not work in practical human communication
