We’ve recently seen a rise in Sock Puppets here at MusicBrainz. We’ve observed editors creating separate sock puppet accounts who vote through the edits of the editor in order to get changes through MusicBrainz faster. This practice obviously side-steps our peer-review system, and up until now we’ve had to have other editors go through and follow the trails of naughty editors to clean up after them.
To avoid this from happening continually, we’ve update the main server with a minor patch that requires people to have more than 10 approved edits in order to vote on other people’s edits. This makes creating a sock-puppet account much harder — each sock puppet account created will need to have a lot of work invested in it before it can be useful. We’re hoping that this simple tweak will discourage sock puppeteers.
