The point of an insignificant spoofing attempt, if it isn't just ideological (and ignorable), would be to try to convince more people to do it (i.e. install the GreaseMonkey script).
Put it this way - say Richard Stallman suddenly decided that companies collecting analytics data and profiting by it (Ooyala doesn't sell it exactly, but we profit by it) was a bad thing and people needed to install a GreaseMonkey script, analogous to an ad blocker, that sent back bad data (wrong URLs, repeats, garbage, etc). That would be an individually-insignificant spoof which was potentially nasty in aggregate.
If designed well, it would also look an awful lot like a high level of background noise, but otherwise condition normal.
