When messages are sent with the noarchive flag, they seem to often repeat earlier API commands or messages after a period of time. This makes the feature lose all its intended functionality as it can't be relied on. For an example, one could take my  TrackerJacker script and activate the archive  @LN85   flag. Use the script to move around the tracker, add statuses/favorites, eventually strange behavior occurs. Turn off the flag and observe that nothing is amiss. The only use of the flag is to enable the noarchive feature  @LN2824 . You can also duplicate this with any script by augmenting sendChat with the no archive feature.
