This user account is a pywiki-based bot operated by LA2 (talk). It is not a sock puppet, but rather an automated or semi-automated account for making repetitive edits that would be extremely tedious to do manually.
Administrators: if this bot is malfunctioning or causing harm, please block it.
I use the pywikipedia framework, manually assisted, to do large numbers of similar edits. I have bot accounts on several languages of Wikipedia.
