Lots of matches and lots of data to look through if one was to fish for suspected duplicate accounts. In my opinion, this plugin would be a lot more useful if the fingerprint list highlighted (or prioritized) matching devices if one of the members is/was banned and/or silenced. There are very few reasons people will set up secondary accounts when not banned, but banned members will always try to sneak in. Having this show up on the list would most likely make this plugin more useful.
I disagree with you on that. Sockpuppeting can be a major problem in some communities. Also, some users are more prone to do that kind of thing, almost wherever they participate. I’ve personally seen it.
I’m also not sure about the “always try to sneak in” when it comes to banned members.
Now, this doesn’t say your suggestion can’t be useful.
I’ve had one new link spammer come in with five sockpuppet accounts before any of the accounts were banned. It’s real. I’d expect that almost any site that gets search traffic and has open sign-up probably is getting SEO spam sockpuppets; the only question is whether admins are finding it.
@udan11 one more suggestion after having used this plugin more: In the list of users matching a fingerprint, I keep on clicking on users’ avatars, expecting them to be links to their admin pages or profiles, so that I can easily investigate whether they are accidental matches or actually sock puppets. I’d suggest admin page would probably be more useful for that investigation, but either would be easier than reading the hovertext, memorizing their user id from the hovertext, then hoping I type it right in user search to finally get to their actual user data.
It turns out that my spammers aren’t using iphones. We use data explorer to look for the “start with innocuous text and later edit it to be link spam” attacks, and fingerprint has done a good job of helping identify those spammers and help us shut down attacks faster. Not making the argument that it should be included by default; I don’t like collecting PII and don’t collect it without cause. If we didn’t have a spammer/troll problem I would absolutely not want to be using it, not because it’s nefarious, but because I don’t want to collect PII without a need related to providing service. So I think that it’s useful but also it makes sense to me that it’s a plugin rather than core. Making it be a conscious choice is a win for privacy. I asked my whole mod community about how they felt about it before implementing it, and was glad to have that conversation up front.
