Yes, you are right.

Do we need to think now about how to reduce the incidence of false
complaints, or shall we wait and see if it's a problem in practice?

One could imagine, for example, if false complaints tended to be 3rd
parties complaining about certs for topsites, we could establish a
registry of "valid complainants" for topsites, such that a complaint
about something.foo.com could only come from the contact in the
registry, and all others could be discarded.

Just brainstorming...
