The good reason happens to be that this admin refuses to have any way but his own the article. Isn't it policy that someone involved in a dispute should not page lock anyway? The history of the page should be evidence enough plus edits by another anon here:  Note not a single comment has been left about why my additions weren't suitable. Please reconsider the page unlock it was locked purely because the admin, for unexplained reasons, refuses to admit new information into the article. Mr. Connolley, if you have any sense of fairness you will unlock the page and allow new contributions. There is no reason not to.
