Kerry, thanks for kicking this off. One update on our end:

There is a general alignment between a few different teams/departments
in WMF that this is an important problem to support chekcusers with in
a better way than what we do today.

I gave a presentation in Wikimania about the research on sockpuppet
detection [1] which is primarily conducted by Srijan Kumar. The goal
of the research is to build models that use public data to identify
accounts that are predicted to be sockpuppets as soon as possible.
Srijan has made significant progress on this front and we'll be
presenting the results of the model to checkusers shortly to get their
feedback. Check out the slide deck [3] if you're interested to learn
more. More updates about the project will appear in [3].

Best,
Leila
