I'm trying to do everything by the book, and I see flagrant examples of violations such as link buying. I report it when I find it (not that Google does anything about it). Reporting takes just a few minutes.
I had ROS anchor text links on a blog that belongs to a friend of mine. They looked like paid links, but were not. After Panda, I asked him to remove them, as I thought that could have been a factor.
I have no more compunction about reporting somebody who's outranking me using techniques that are against the rules than I do reporting stolen credit cards. Both are attempting to harm me by trying to game the system.
