Robot 9000 is a script used in the xkcd-signal IRC room. Yes, i know IRC is different to messenger. I was wondering if a possible adaptation would be possible. It would require that all messages (incoming and outgoing) be compared to a log of all previously sent messages (to a single user). Then, if a message appears twice (if you repeat yourself) you are prevented from sending a message for a period of time.
The whole idea of this is to encourage originality so as to prevent crappy conversations full of 'sup man' and 'nothin much.'
