How is asking "was that for
N12345?" less troublesome on a busy frequency than calling "Blocked" or
better yet, not saying anything at all and waiting for the controller to
call again?

IF you're not sure or it definitely was not for you, then saying

I also find one "blocked" often leads to another "blocked" as the
"blocker" "blocks" you again as you (the controller) key up. Who's
to say who should speak next after a "blocked"? Whoever last keyed,
and it takes two or more to be "blocked", will assume they were
the "blockee" and will key again (pilot or controller) to get across
what was "blocked".
Sort of on this topic is another favorite transmission of mine, this
coming from controllers: 2 or more aircraft call at the same time,
response: "two called at once, say again". Shocker, two call at
once again. Hilarious.
