It seems to me what people are complaining about isn't the false positives, its the fact that there aren't proper channels to address the issues - and your basically a hostage till someone at Google decides to take pity and talk to you.
This. Reality is going to cause false positives. While you can try to minimize them you'll never get rid of them.
The measure of a system is how they are dealt with. Note that this is not limited to Google by any means. I'm thinking of the police throwing some people in jail as terrorists because they pinged on a geiger counter. Cancer patients, not terrorists. Compare that to what happened when my wife tripped a detector in China. The officials knew it was almost certainly a false positive and were looking for why rather than playing gotcha. (However, I think they went too far in the other direction--it was due to a nuclear heart test, but they didn't even doing the simple test of seeing what the distribution of the radioactivity was.)
