English wiki Unsourced BLP Drama Pragmatic Review
From what i'm trying to do in En Animanga project. You make a "Call for arms" within your project to clean up the project unsourced BLP. You keep account on who fix what and award Cookie, Barnstars and whatever form of recognition on based on participation, on numbers of fixed articles, most fixed articles among project members, ...
That's somewhat similar to what Animanga did to make project whole assessment.
Had i been me, i would have created a set of Barnstars exclusively for the unsourced BLP clean up awarded depending of editors degree of involvements. The different projects will award them but the set and the criterion to award them will be the same. The objective is to create the feel that you contributed to a small chunk of the collective history of En Wikipedia and it what happen ever again. In others words an I was there feeling.
What it's baffling is that editors are volunteering to clean up the shits source the articles and some people consider those editors support as a given. The threat of mass deletion might give them that feeling and some editors are de-facto blackmailed to fix those articles. However you know as i that there will be other days and others battles, and in those times what was thought as granted will be sorely missing.
