This is an incredibly confusing statement. No one can be added or removed
from a ballot after the votes have been counted, so by this distinction
there is no such thing as an IIA spoiler.

More precisely, the "adding and removing" of an alternative is an alytical
trick that helps prove attributes of a method from a logical standpoint, and
has no meaning with regard to real elections.

ICC is just a weaker version of IIA, and has to be weaker because nothing
can pass IIA and meet three other desirable criteria.
