Given the number of people working in computer science and the fact that publishing papers is considered the goal of our work, there is an insane number of papers written every year, the vast majority of which contribute very little (or not at all) to our collective knowledge. This is basically spam. In fact, for many papers (including some of my own), the actual idea of the paper could be stated in one paragraph, but somehow people manage to write 10 pages of it.
