I touched this a bit earlier, but it is worth bringing up again. We, as a society, are running around with our pants down around our ankles and are not even aware of the breeze. This database has been done more or less by a guy goofing off, any serious bad guy has done the same thing in a week with access to any number of bot nets that can be rented (or trivially manufactured). The sorts of scans that are necessary to collect this information are so ubiquitous that it is not worth even logging the attempts to try to establish a pattern. If you are out of reasons to lie awake at night, shivering in terror, this one should jump right to the top.
