man page for 'blacklistd.conf' has typo "prococol".
Oh, and the sentence following says "the fourth file" instead of "the fourth field".
The next paragraph "are controlling" could be simply "control".
FreeBSD actually imports blacklistd. Its canonical source is NetBSD. Please report this bug upstream instead.

blacklistd.conf.5: typo/grammar fixes
Submitted by: Mike Lempriere
(In reply to Alan Somers from comment #2)
That is true, but I have incorporated a number of blacklistd minor bugfixes or improvements into FreeBSD and coordinated with Christos @ NetBSD for upstreaming. I committed these changes to FreeBSD as r361230 and let Christos know.
