Yes - "scam", "complaint", "rip-off", and "problem" are the most common. As far as I can see, this is a very important issue that Google needs to actively address -- rather than defending their status quo. The French courts agreed, although I understand that an appeal is still in the works.
When reputations can be inaccurately damaged by an algorithm, then those who wrote that algorithm need to re-write it. Algorithms are not an Act of Nature, after all, they are the act of people. And really, how much would it hurt Google's product not to "suggest" these critical terms at all.
