If the SPAM is not coming via SCRoots, then the problem should be taken up directly with the source of the SPAM, or with your Internet Service Provider, or your better business bureau, or your local or state law enforcement, or your attorney, etc. I find this observation interesting. People generally want taxes reduced. Yet, they also want the government to increase services. You can't have it both ways.
Services cost money.
Money comes from taxes. Establishing a new office in the federal government to receive, study, investigate, and take action on the millions of complaints from citizens who receive SPAM will cost LOTS of money. The existing network of Internet Service Providers already have a technically competent staff which could provide the same, or better, service in most cases. There are also anti-spam programs and filters available which can be installed and configure by each individual. My personal opinion is that the federal government should become involved when the matter involves national interests.
