This is a wonderful example of the fundamental flaw with this class of
argument that I mentioned before.
Why assume that only the A voters would attempt to manipulate the
election by changing their votes?
If the B & C voters, who certainly prefer D over A, get a hint that the
A voters are attempting to manipulate the election, they can bury A and
promote D and give D the victory - 500 to 499, which was the sincere
outcome to begin with.
