A Kimberly fan harmlessly anonymously trolling with comments (annoying to some, but no map vandalism).  An active participant, unlike spammers who would plaster the map with self-promoting advertising and not respond.  Can safely be ignored; I've had my fun feeding the troll and should probably suffer the consequences of encouraging him/her, by a zero-day block for the next decade or four.
(Mostly harmless compared with, oh, some latin american countries where notes/bug-reports are practically useless)
