My own sins: fewer and far between. I publish the "same" article in multiple venues. Cognizant of the difficulty, I always make some small change and (usually) reference that fact. But I am aware of the fact. With informal writing, it is not a big deal. With Federally-funded scientific research it is a big deal. Even if the writing is new, re-using an illustration will force a retraction.
People have done to prison. Just put "researcher went to prison" in your search engine.
On my passive blog, CSI:Flint 2010, I was inspired to bring the Office of Research Integrity to middle school students who were interested in science and police work. "Don't waste your motivation on CSI," I said. "That is like the physics of Star Trek. If you love science and want to do police work, go for the Office of Research Integrity."
