Err ...
I find it very hard to believe that you have *ever* nominated an article for AfD and seen it kept, either by AfD or DRV. Please don't bullshit us, it's very tiresome.
That's "pure vandalism article", of course, not "article".
I find it *very* easy to believe that Cobb might have nominated good articles and seen them kept, but it's rather unlikely he's ever stuck a pure vandalism article on AfD and not had it deleted.
Bah.
