Hi,
To point out the problems with the latter; the deleted form of the Seigenthaler article wasn't categorised by anything, wasn't tagged as a stub, and wasn't phrased in the standard fashion for a biography ("[name] (year-year) [is/was]")... so there's no obvious automated way of picking it up.
On the category, you have just defined a "suspicious article" haven't you? Particularly the "wasn't categorised by anything" bit.
