Wikipedia says the Killfile was first in Larry Wall's 'rn', but
doesn't say which rev it was added to; implies that Jerry Pournelle
was the feature request in 1986, so likely about then?

A little closer to Spam control, the Usenet Cancel Index dates to c.
1994-09-30 per
   https://en.wikipedia.org/wiki/Breidbart_Index
which has footnote [1]  that links

(Anyone wishing to dig further into that, the eponymous Seth still has
same email address via Panix. Saw him just this last Saturday at a
Scotch event. MAP would approve.)

The Killfile.org archived Usenet FAQ doesn't appear to have history
going back far enough to answer anything, but likely has useful
reminders.
