Seems weird he mentioned Spike Lee (who did nothing wrong, as far as I can tell) so many times, but didn't name the agency. Seems to hurt the wrong party's reputation.
Additionally, he has no apparent way to contact him.
EDIT: I really don't want to point fingers with 0 proof, but Spike Lee happens to be CEO of an ad agency named Spike DDB. https://twitter.com/SpikeDDB
