This section of the BLP is kind of rot: ---- Editors should remove any contentious material about living persons that is unsourced, relies upon sources that do not meet standards specified in Wikipedia:Verifiability, or is a conjectural interpretation of a source (see Wikipedia:No original research). Where the material is derogatory and unsourced or poorly sourced, the three-revert rule does not apply. These principles apply to biographical material about living persons found anywhere in Wikipedia, including user and talk pages. ----
What if the material is accurate and can be checked with a quick google search? Wouldn't a better formulation be: ---- Editors should add proper sources to contentious material about living persons. If such a source cannot be found, the material should be removed. Where the material is derogatory and unsourceable, relies on improper sources (see Wikipedia:Verifiability), or is a conjectural interpretation of a source (see Wikipedia:No original research), the three revert rule does not apply.
Derogatory opinions about living persons on user and talk pages must follow the above rules. Contentious or negative biographical material on user and talk pages must be verifiable. If properly contextualized, contentious material from questionable sources may be discussed, but the problems with the material and the sources must be clearly identified, and such material may be removed if the discussion has ended or is not contributing to the development of the article. When in doubt, derogatory material that is not properly sourceable should be removed. ----
