I agree with this.  I run a artwork voting system on a very popular site and
before I wasn't checking to see if the values of the votes (I would add up
the scores and divide by the # of votes to get an average) were between 1-10
which was on the HTML form.  Much to my surprise I found several scores at
1000 and several scores with values BELOW 1 trying to bring down competing
pieces of art.  Obviously someone had re-written the form and this is a site
catering to 13-25 year olds.  And there was no profit motivation either.

I think you're overestimating the difficulty of rewriting HTTP headers. I
think you're also underestimating the population of computer criminals.
