Situation: Sockmaster, very persistent, has been going for a month plus, editing from a major city's public library system using IP accounts initially but creating up to several named accounts per day more recently.
Articles have been semi-protected in many cases, but... I am wondering if it would be considered abusive to do a "can't create new users from these addresses" IP block on the range of IPs used for those libraries.
That's not "all edits blocked", just "can't create new accounts".
