I just did a check on a client's competitor who is always doing something like this and sure enough 9 out of top 10 SERPS are owned by this person, including 2 of his new domains, his facebook page, his blogspot blog, a PR release, his wordpress blog, etc.
I just reported this on Google's feedback form and the Post Penquin spam form. If enough of us do this then maybe Google will do something about it.
