Q on HTTP/1.0 Sec. 11.2 Idempotent Methods

I just finished reading <draft-ietf-http-v10-spec-00.ps>, dated March 8, 1995,
and found it to be a very understandable document for the most part.  However,
I don't understand this sentence in the second paragraph of section 11.2:
    The link "click here to subscribe" -- causing the reading of a special
    "magic" document -- is open to abuse by others making a link "click
    here to see a pretty picture."
Perhaps my confusion is due to the first paragraph which encourages clients
to behave responsibly. If I understand correctly GET and HEAD are interpreted
by the server, so the client can't misuse them?

You may want to clarify this issue for the next revision of the document.
