These names were pulled using the criteria outlined above and nothing else. This means that nearly all of them ultimately had nothing to do with it. It was still interesting for me to attempt to do. With that being said and unless I have misjudged the nature of the other offices/officeholders in the game, I'm nearing 100% confidence in saying the perpetrator is on this list.
of these, i think türkisblau ("i'm just having fun with trying to plot things.") and bmotley (who has previously been banned for sockpuppetry) are the most likely. could be wrong of course
