This user account is a bot (a pywikipedia bot, more exactly) operated by User:Riccardo
(Riccardov on it.wikipedia and riccardo on IRC #wikisource or #wikipedia-it)

It is not a sock puppet.
Administrators: if this bot is malfunctioning or causing harm, please block it and then send owner a message

This is a non-flagged bot for now, I am asking for a flag, bot is already flagged in en.wikipedia and it.wikipedia (w:User:Riccardobot and w:it:Utente:Riccardobot). See Wikisource:Bots.

Catholic Encyclopedia (1913) is now complete, bot is paused until some mass-changes will be needed
