A10:Any biography of a living person, created after 1st April 2009, which has no credible sources whatsoever, and has been tagged with {unreferenced BLP deletion} for at least 5 days. Administrators should check that the creator has been given adequate notice. (Note that any article deleted under this criterion may be summarily undeleted by any administrator if any editor indicates a willingness to source the article).
Template {unreferenced BLP deletion} should read: "This article on a living person lacks any sourcing. Please edit this article to provide sources. If this article is not sourced by [day-month-year] it may be subject to deletion. Do not remove this template unless sources have been provided.".
I have to say, the most saddening opposing argument comes from DGGÂ (T-C-L-K-R-D)
who apparently believes this is "an almost non-existent problem". Tens of thousands of unsourced BLPs, but he thinks there's no problem. He's also the gnat of this discussion, buzzing around the support votes to add the stupid idea that it should become administrative responsibility to source BLPs, rather than putting the responsibility on the author, as is policy.
