Unfortunately, actions like these do not knock off spam for long. iirc, the last time a major spammer was knocked offline, the result was a sharp drop for a day, then a return to pre-action levels. We're better off making spam a less profitable venture, and thereby letting the market reduce the number of people turning to spam as a source of income.
