Well, perhaps person A just should refrain from offering more
than he can support... People expect a technical solution to 
everything, when user education would be more in order.

Then what? People might query with a hash. Do you plan to send
them some kind of "busy, come back later" -message? When would
that later be? Or perhaps "no, this file is not available 
at the moment. Get another."? But which one? If we tell,
that'd be... telling. When would the node respond to 
searches with locally inserted matches? Suppose it did, 
when there was little load. Now the results would propagate
and be available to people (supplied by other nodes) even
when there was load on your node and you were unable to
supply the file, having to denyfileupload.

I don't say it can't be done. I don't say it shouldn't
be done. Only that its complicated and it just might not be
worth it. Inserting lots of junk in a way pollutes the 
keyspace and makes it harder to find 'the good stuff'.
Perhaps it would be better to insert a little excellent
stuff and support that.
