I guess it makes you feel bigger and better to be an @sshole on a public
mailing list but I don't think that anyone is impressed with the fact that
you aren't offering any better ideas; just name-calling and showing a low
maturity level.

Just wasted time, space, and email if you aren't going to provide a
solution or try and fix the script.

I could be wrong, but doesn't last/lastb show users have have logged
in/out.  Therefore it wouldn't necessarily catch brute-forcers (unless
they were actually successful)?

This guy was just trying to be helpful and demonstrate a way of blocking
(or attempting to block) brute-forcers.  You aren't providing any value,
just being a d!ck.
