User blog comment:The Ultimate Thinker/How to catch a Sock Puppet?/@comment-5111452-20140817140228/@comment-26479628-20140818140557

If the sockpuppet you mentioned isn't doing any harm, it's as crucial to catch them as one who is making accounts to attack the wiki. Like, if the sockpuppet doesn't commit malicious editing, and is pretending to be 2 different users, it's not like you have to catch them, as they aren't doing too much damage per se.
